The Blues already look set to finish third in the league whilst the Irons’ fate is still uncertain with Wolves and Manchester United also in the hunt for sixth place.
David Moyes’ men will take confidence from the fact that they beat Thomas Tuchel’s side 3-2 in the reverse fixture with every remaining game now vital for the east London club.
With a crunch first leg of their Europa League semi-final against Frankfurt on Thursday, will the Scotsman prioritise Europe and look to make changes against Chelsea? Here is how Football FanCast expects the Hammers to line up.
West Ham XI: Fabianski, Johnson, Dawson, Alese, Cresswell, Soucek, Rice, Bowen, Lanzini, Benrahma, Antonio
As expected there’s no change in goal as Lukasz Fabianski continues his role as league goalkeeper whilst there’s a major change in the defence with Issa Diop now ruled out with an ankle injury.
With Craig Dawson the only fit senior centre-back, we expect Moyes to finally give an opportunity to exciting youngster Aji Alese.
Moreover, the 21-year-old is a left-footed centre-back so should slot in next to Dawson perfectly as he gears up to make a potential Premier League debut.
Tomas Soucek and Declan Rice are set to continue their partnership in front of the back four whilst there is another change in the attacking midfield trio with Moyes playing his usual 4-2-3-1 set-up.
Nikola Vlasic was handed a rare league start against Burnley last weekend and failed to deliver once again, therefore we expect the Croatian to be replaced by Said Benrahma to add much-needed creativity to the side and support for striker Michail Antonio.
Despite playing a London rival in Chelsea, this afternoon’s match is crucial if West Ham are serious about securing a top-six finish, with other sides in the hunt breathing down their neck.
