The England global, on loan from Manchester City, has not had the desired impact in his temporary move to the London Stadium, and reports this have now suggested that Hammers boss David Moyes will take Hart out of the starting lineup and replace him with Adrian.
Moyes is also set to stick with Adrian in goal with Joe Hart facing being dropped after the Spaniard's impressive display at the Etihad.
Carton Cole says West Ham can't afford to wait for Joe Hart to rediscover his best form.
Moyes won't want to bring his star striker back too soon, especially with the Christmas period on the horizon and a busy set of matches to come, but he may be forced to play him on Saturday. He is trying to find his form but can West Ham afford to be waiting around for Joe Hart to show his form?
But Moyes says Hart is going nowhere: "I don't think we could work here without two top goalkeepers". I would definitely want the two goalkeepers.
"I'll keep my team until tomorrow". I do believe, though, that you have to have some consideration for the players involved and any decision I make will take due account of their welfare. But he's not guaranteed, just like there's no one guaranteed.
"I would always try to speak to the players".
"But we've still got to do a number on them because they have shown already that they will lie down, but they won't lie down unless you force them to and put in that performance that they surrender to it". West Ham will likely concede at least once, they've only kept three clean sheets all season, so they'll need someone to create some scoring chances for them and Lanzini is their best bet.
It is worth noting, though, that there have been goals at both ends in just one of the last 13 competitive matches that West Ham United have won on home turf - a run of results that stretches back to the beginning of last season - while both teams have scored in just one of the Blues' last five matches on their travels. I would like those problems in a few other positions.
