Both won their opening game, with Lens needing two injury-time goals to beat Slavia Prague while Sporting beat Galatasaray 3-1. The hosts are slight 6/42.50 favourites and have only lost twice in 29 European games at home - but they've not kept a clean sheet in 14 Champions League games now.
Sporting are 17/102.70 and don't have a great away record in Europe with just one win in nine, but they're unbeaten away in 10 in all competitions and haven't lost a game yet this season. Goals have to be fancied as six of Lens' past seven saw both teams score while 12 of Sporting's past 14 have contained over 2.5 goals.
Five of Sporting's last eight have been draws and this could go the same way with these two sides seemingly evenly matched.
Slavia will fancy a bounceback as they head to Azerbaijan as 21/202.05 favourites against tournament newcomers Sabah, and although the Czech league leaders haven't won in the UCL proper in 20 games this is one of their best chances for some time.
Sabah are 5/23.50 and for a club that's is not yet 10-years-old just being in the competition is an achievement. Slavia's extra experience at this level really should tell, with their record they're a touch hard to trust but odds-against we'll give them the benefit of the doubt here.
Back Slavia Prague to win
Arsenal shouldn't have any problems here as 2/91.22 favourites with a stellar record at this stage, winning 13 group games in a row and losing just two of 31. Lille lost to Betis last time but have won two of three away games this season, and both with a clean sheet.
They've won nine of 11 on the road but haven't kept a clean sheet in 12 UCL away days. Arsenal on the other hand have 18 clean sheets in 24 European home matches and another one should be on the cards here even with Olivier Giroud returning to the Emirates.
Mikel Arteta may make a few changes here so we'll just play it safe on Arsenal just being Arsenal - which is winning without conceding.
Drawing with 10-man Spurs is not exactly great form to take to Atletico Madrid for Man Utd, who are 13/53.60 in the Spanish capital with Diego Simeone's men 19/201.95 favourites. Atleti have won four straight since losing to Liverpool, but they're on a bad run against English sides of late with a W2 D3 L10 record recently.
This Atleti side is a far cry from the defensive, tight former Simeone teams with goals going in everywhere, and early goals have been a feature in this competition with first-half goals in 11 of their last 12 UCL group games.
The way they play now could actually help Michael Carrick's side, who look far better on the counter than having to force the issue. Both teams scored in the first half in Atleti's last game and also at Anfield against Liverpool. I can see that coming in again.
Back both teams to score in first half
Gala only got on the scoresheet with an own goal in their defeat at Sporting, but they did all their damage at home last season by beating Liverpool and Juventus and drawing with Atleti. They're a massive price though at 8/19.00 as Barcelona arrive in red-hot form.
Hansi Flick's side have opened up the season with nine straight wins, which even the mighty Barca haven't done since 1935, so they're 1/41.25 to keep that 100% record going. Barca simply can't keep a clean sheet in Europe though and if anyone's going to score for the hosts it's Victor Osimhen with seven goals in 10 UCL games for the Turkish side.
Back Barca win and both teams to score, Osimhen anytime scorer
Inter are pretty short here at 1/41.25 considering they've lost three in a row in the Champions League, but their opening defeat at Real Madrid was no disgrace and they've won all four home games this season scoring a total of 15 goals and at least three in every game.
Brugge can be handy in Europe but they're 10/111.00 and have real problems defensively, as they've conceded 3+ goals in seven UCL games since the start of last season - that's the recipe for defeat in Milan. On the plus side for the visitors four of Inter's last five have seen both teams score.
Back Inter win and both teams to score
Leipzig are a tricky team to get a handle on, as they've mixed 5-0 and 6-0 wins with 3-1 and 4-1 defeats. At home though they've been dominant with those 5-0 and 6-0 wins along with a 3-0 victory in a flawless start. So no wonder they're 8/111.73 home favourites.
This PSV side is also full of goals - scoring 23 in seven - so even at 3/14.00 and with the German side's home record the Dutch visitors are more than lively outsiders. And although Leipzig haven't conceded a home goal in the Bundesliga they've conceded in their last 18 UCL games, while eight of PSV's last nine have seen both teams score.
Back RB Leipzig win and both teams to score
Viking have won their last 11 games at home but lost 3-1 to Stuttgart on matchday one while Bayern beat fellow Norwegian side Bodo/Glimt 5-0 - and for comparison they have an identical league record to Viking. So expect a similar result with Bayern 1/121.08 and averaging 3.3 goals per game in their unbeaten nine games against Norwegian sides.
Bayern have conceded in their last eight UCL aways but they score enough goals to suggest they can run away with this one.
Back Bayern -3 on the handicap
Villarreal lost to Dortmund 3-2 in their opener, and a 1-0 defeat at Real Madrid at the weekend was another decent display. At home there's been plenty of goals but only one win so far - they're 6/52.20 to win a second of the season.
Napoli lost out to Arsenal at home in the first round of group games but won 3-0 at the weekend to head to Spain full of confidence. There was just four goals in their preceeding three games and they're 9/43.25 to add an away win. The way the teams match up though this one has the hallmarks of a tight draw.
