Spain vs Portugal, 19:45 BST, Live on BBC1
Match Odds: Spain 1.981/1, Portugal 4.77/2, the draw 3.55/2
22:35
Truth be told, this was a stinker, but credit goes to Spain for showing the stuff of champions to get the job done. Portugal looked dangerous at times but faded badly in extra-time, and Ronaldo failed to stamp his authority on the contest.
Spain are obviously now favourites to win the competition, but I don't think Germany or even Italy will find much to fear from this display. I'm off to Pillowtown - tomorrow you'll be in the capable hands of Mike Norman for Germany vs Italy. Enjoy!
22:30
So Spain squeak into the final by the narrowest of margins, and are on course for a third consecutive major title. Portugal are left to rue the decision to put defender Bruno Alves ahead of Cristiano Ronaldo in the shoot-out list. Alves unsettled himself by trying to take the third penalty instead of Nani, and when it came to him taking the fourth, he looked desperately nervous.
22:27
Fabregas pen hits inside of post and goes in. Spain win shoot-out 4-2 and reach EURO 2012 final.
Bruno Alves pen hits bar. Spa 3 Por 2.
22:25
Ramos scores Pirlo-style. Spa 3 Por 2.
Nani pen scored. Spa 2 Por 2.
22:22
Pique pen scored Spa 2 Por 1.
Pepe pen scored. Spa 1 Por 1.
Iniesta pen scored. Spa 1 Por 0.
Moutinho pen saved. Spa 0 Por 0.
22:20
Xabi Alonso penalty saved. Spa 0 Por 0
22:17
If we use England as a yardstick, Spain lost to them on pens at Euro 96, while Portugal beat them twice in shoot-outs.
22:15
It's penalties, boys and girls. It's simple now - Spain 1.875/6 in the To Qualify market, with Portugal 2.1211/10.
22:12
Pedro weaves his way into the Portuguese box, but he can't find a team-mate. Penalties looming.
22:09
Fabregas plays in Pedro, but he dwells on the ball too long, and the chance is lost. Spain 2.285/4 to win on penalties, Portugal 2.68/5.
22:07
Varela on for Meireles. A suprisingly attacking change from coach Bento.
22:05
Arbeloa finds Navas in the box, who tests Rui Patricio with a low shot. Patricio gathers the ball at the second attempt, with help from Pepe.
22:03
Portugal's only two penalty shoot-outs at major tournaments have been against England (won both).
22:02
Two of the last three wins by sides in the second half of extra-time at the Euros have been against Portugal - both times France (Euro 1984, Euro 2000).
22:01
In the ET Correct Score market, 1-0 Spain is 5.39/2, 1-0 Portugal is 10.519/2, 0-0 is 1.4640/85.
21:57
Sergio Ramos belts a free-kick a lick of paint over the bar. Half-time in extra-time. Still no goals.
21:55
Jordi Alba works some magic on the left, and crosses for Iniesta. His shot is superbly turned away by Rui Patricio.
21:51
This is tired, yawn-inducing stuff, so let's distract ourselves with the ET Next Goal market. Spain 4.131/10, Portugal 6.411/2, No Goal 1.654/6.
21:47
Iniesta strikes a fierce shot which is charged down. By the way, I forgot to tell you Pedro replaced Xavi just before the end of the 90. No Torres.
21:45
Now that the Match Odds market has closed, we can now perhaps look at the To Qualify market, where Portugal are 2.3411/8, and Spain are 1.738/11 favourites. I think the game's dead even myself.
21:40
Back underway. Portugal have played extra time in two Euros semi-finals previously - they lost both games in extra-time.
21:36
We're heading into extra-time. In the Qualifying Method market, Spain are 3.6553/20 to win it in extra-time and 3.211/5 to win on penalties. Portugal are 5.79/2 to win in extra-time, and 3.711/4 to win on penalties.
21:33
As we move into stoppage time, Meireles plays in Ronaldo, who fires over left-footed.
21:28
Ronaldo blasts another free-kick over. Bruno Alves goes into the book.
21:22
Portugal bring young striker Nelson Oliveira on for Hugo Almeida. In the Next Goal market, Portugal are 8.415/2, Spain are 5.49/2, with No Goal the clear favourite at 1.384/11.
21:15
Ronaldo fires a dipping 35-yard free-kick just over the bar.
Incidentally, Jesus Navas's two goals for Spain have both come in the last five minutes of games. He's 22.021/1 in the Last Goalscorer market.
21:11
Seven of Spain's last 11 games that have been goalless at half time have ended in a 1-0 win. A 1-0 Spain win is 4.77/2 in the Correct Score market.
21:07
Joao Pereira hauls down Fabregas on the edge of the box, and is booked for his trouble. Xavi's wickedly delivered free-kick is headed clear by Almeida.
21:05
Jesus Navas replaces David Silva for Spain. Pepe and Busquets have both been booked.
21:03
Portugal are starting to look really dangerous on the break, and they are 5.69/2 to win, with Spain 2.982/1 and the draw 2.01/1.
21:00
The ball breaks for Hugo Almeida 35 yards out. He has Ronaldo and Nani in support, but ignores them both, blazing a shot over the bar.
20:56
The first substitution is made, as Cesc Fabregas replaces Negredo for Spain. He's been dreadful.
20:51
For those of you who are keeping an eye on the corner situation, Portugal are currently 3-0 up.
20:48
Back underway at the Donbass Arena. No half-time changes - Negredo's a lucky boy. I might as well have played for Spain up front for all the difference he made.
20:44
While the first half was interesting, it hardly set the pulses racing. We only had one shot on target, the joint-fewest in a half at EURO 2012 so far. Under 1.5 goals is currently a stingy 1.548/15, with over 1.5 goals 2.8415/8.
20:40
To illustrate the pressure Spain have been under at times, Opta tell us that the defending champions made 14 first-half clearances, while Portugal had to make just two.
20:37
Spain are now out to 2.466/4 to win in 90 minutes, with Portugal 4.94/1 and the draw 2.526/4. Bearing in mind that Portugal have disrupted Spain's rhythm and pressed them hard, 4.94/1 looks decent.
20:33
Fabio Coentrao stupidly booked for a bit of back-chat. Silly boy.
The half-time whistle is then blown. It's been intriguing rather than incendiary so far in Donetsk.
20:29
Spain look nervous at the back, and Pique has a let-off as he fails to intercept a long ball which barely eludes Almeida.
20:26
Sergio Ramos is booked for cynically taking out Ronaldo.
20:24
David Silva approaches the Portugal box, but fails to find Iniesta when he could have shot. Incidentally Negredo has shown all the movement of a tree so far.
20:20
There haven't been many chances, but if you fancy Both Teams to Score, it's trading at a tempting 3.052/1.
20:17
Ronaldo misses the right post by a whisker after a nice shimmy on the edge of the box. He's up for this, make no mistake.
20:14
Iniesta curls an effort just over after good work from Negredo. Of Spain's last seven games, four have been goalless at half time, and the other three have been 1-0 in their favour.
20:11
As Ronaldo skies a long-range effort, 0-0 in the Correct Score market is trading at 5.95/1. 1-0 Spain is 5.69/2, 1-0 Portugal is 9.89/1.
20:06
Portugal will be satisfied so far, but they would like to carve out a chance or two. 0-0 is currently 1.9720/21 in the Half-Time Score market.
20:01
Here's a thought - Ronaldo has had 64 shots from outside the box in major tournaments, and hasn't scored from any of them.
19:58
Spain 1.991/1 to win, Portugal 4.94/1 and the draw 3.39/4.
19;54
Spain's Alvaro Arbeloa misses the first chance, blazing over when well-placed.
19:51
Spain have won all 11 games with Alvaro Negredo playing, averaging 3.18 goals per match.
19:49
Casillas has to tip away a Veloso corner, and then confidently claims the next from Meireles. Good start for Tobias Gourlay's pro-Portugal corners bet.
19:45
They are underway in Donetsk.
19:42
Cristiano Ronaldo is 7.413/2 in the First Golascorer market, and 7.26/1 in the Last Goalscorer market.
19:38
Food for thought for Iniesta fans - only Karim Benzema (19) has had more shots without scoring than Iniesta (15) at Euro 2012.
19:33
If you think we're in for a long evening, I suggest you pop over to the Qualifying Method market. Portugal are 20.019/1 to win in extra-time and 13.012/1 to win on penalties, with Spain 11.010/1 to win in the extra half-hour and 12.011/1 to win a penalty shoot-out.
19:28
The way the Over/Under 2.5 goals market is priced up suggest we're in for a tight affair, but if you fancy goals, Over 2.5 goals is a healthy 2.68/5.
19:23
Our good friends at Opta have sent me some stats. Here's a little selection for you.
Almeida for Postiga is the first time Paulo Bento had made a change to his starting XI at Euro 2012.
Portugal have had the most attempts from counter-attacks at Euro 2012 (six).
Only three teams have had more shots than their opponents in every match at Euro 2012: Spain, Portugal and Poland.
19:20
Spain also make one change, and it's a bit of a surprise, as Sevilla's Alvaro Negredo plays as a genuine striker instead of "false nine" Cesc Fabregas.
Spain: Casillas, Arbeloa, Pique, Sergio Ramos, Jordi Alba, Xavi, Busquets, Alonso, Silva, Negredo, Iniesta
19:18
The teamsheets are in at Donetsk's Donbass Arena. We'll start with Portugal.
Portugal: Rui Patricio, Joao Pereira, Pepe, Bruno Alves, Fabio Coentrao, Meireles, Veloso, Joao Moutinho, Nani, Almeida, Ronaldo
One change for Portugal, with Hugo Almeida replacing the injured Helder Postiga in attack.
19:14
If all that wasn't enough for you lucky, lucky people, our La Liga expert Tobias Gourlay has also previewed this Iberian clash. As you'll discover here, Tobias doesn't cut corners, he bets on them.
19:09
Do you like stats? I've got stats, or rather Michael Lintorn does. His Opta preview is here.
19:04
They say the devil's in the detail, and our tactics guru Michael Cox has been scratching beneath the surface on your behalf. As you can see here, he's leaning towards Spain.

18:55
Good evening, my friends. We're all set for a fascinating first semi-final at EURO 2012, as world and european champions Spain take on Cristiano Ronal...er, I mean Portugal. Of course, it's harsh to dismiss Portugal as a one-man team, but Ronaldo's stellar displays have caught the eye of our football ambassador Lee Dixon, and his pre-match thoughts can be read here.
