Chelsea v Hull

Jekyll and Hyde Blues
Chelsea are a strange team this season. At times, everything seems normal and the results flow as you'd expect. At others, they look a mile away with echoes of the side that downed tools when making an appalling defence of their title two seasons ago.
It's summed up in their last four results - a pair of 3-0 wins over Newcastle and West Brom against shock 3-0 and 4-1 reversals to Watford and Bournemouth. Before that run, they'd drawn five in a row so should we have have any trust in them?
Chelsea have Tiemoue Bakayoko, David Luiz and Ross Barkley unavailable through injury which limits the scope for major rotation even though the hosts could well mix it up and give starts to Emerson Palmieri and teenager Ethan Ampadu.
Hull short of numbers
The prospect of back-to-back relegations remains a distinct and horrifying prospect for Hull as they sit 21st in the Championship.
They're certainly harder to score against since Nigel Adkins came in and three wins and two draws in their last seven starts offers some promise.
Two of those wins have come in this competition - away to Blackburn and home to Nottingham Forest - so perhaps they're saving their best for the FA Cup, although Chelsea is a major step up of course.
Their last duel in the FA Cup? A 6-1 win for Chelsea in 1999!
Adding to current woes is that, according to Adkins, they've got no less than 12 players on the injured list. "We need a lot of magic to help us," he said ahead of the game.
Blues too short
Despite the constant merry-go-round of managers and change in personnel, Chelsea tend to get it right in this tournament and have progressed to the quarter-finals from nine of their last 10 fifth-round ties.
Chelsea are just 1.222/9 to triumph in 90 minutes while Hull are 1918/1 to leave the Stamford Bridge crowd stunned. A Draw is 7.613/2.
It's tempting to say that Antonio Conte will have one eye on Tuesday's Champions League showdown with Barcelona but I'm not buying too much into that.
He knows the FA Cup represents by far their most likely source of silverware so will be giving Hull full attention with a Wembley final starting to come into view if they win this one.
If the shadow of the Barca game is to have an effect, it would be prompting Chelsea to start fast and put the game to bed early. In which case, I like the 2.47/5 for Over 1.5 First Half Goals.
Should Hull throw in a surprise early goal themselves, it will hopefully sting Chelsea further into action.
Hosts can keep it clean
In this rather all or nothing Blues world, it looks worth bumping the hosts' very short basic win price up to something near Even money by backing Chelsea to win to nil at 1.9110/11.
Their last five victories have all been achieved with clean sheets and they've shut out the opposition nine times in the last 14 games.
Hull are more cautious under Adkins and have failed to net in seven of their last 12 matches and that's against defences not managed by an Italian Premier League boss.
Overs clear favourite
Over 2.5 goals is short at 1.584/7 but it's only landed in three of Hull's last 12 games and I'm not expecting them to add to Friday night's tally.
Does that mean Unders at 2.447/5 is a play. Not really given that I'm backing Over 1.5 First Half Goals.
Even though Hull may not contribute, it's easy to see Chelsea racking up three or more, something they've done in their last three wins.
Team news could thwart scorer punt
It's hard to put up a bet until the starting XIs are in. If Conte does start with Eden Hazard, there's scope to back him for two or more.
Looking at the 12 games he's scored in for club and country this season, on five occasions the Belgian has gone on to bag a brace. When he's on, he's on. The problem, though, is that he might not even get on if Conte takes the cotton wool option.
Andre Marriner gets the nod for this one. He's shown 67 yellows and three reds in his 24 matches this season but dished out just a single booking to a Chelsea player in two matches in charge of the Blues.
Hull are mid-division in the Championship Fairplay table this season.
In all competitions, the Blues have never lost at home against Hull City, winning 17 and drawing five - winning each of their last four.
