Gianluca Scamacca is back in training at West Ham.

The £30.5million summer signing has not featured since a brief cameo in the defeat to Wolves in mid-January, missing the Hammers' last two Premier League games, as well as the FA Cup victory over Derby, because of a knee problem.

It remains to be seen whether the Italian is ready to face Chelsea, says the London Evening Standard.

Danny Ings, signed from Aston Villa in a £12m deal last month, picked up a knee injury after making his debut as a substitute in the win over Everton but after initial fears he could miss several League matches, the 30-year-old returned off the bench at Newcastle.

West Ham will be looking to build on a recent - and much-needed - upturn in form that has lifted manager Davud Moyes' men out of the relegation zone and into the fifth round of the FA Cup when Graham Potter's out-of-form Blues travel to the London Stadium.
