The 18-year-old January signing from Atalanta was pictured with the Manchester United squad at their team hotel ahead of Tuesday’s fifth-round tie at Old Trafford.
Diallo’s inclusion comes after an impressive start to life at United packed full of promise and flair performances.
It started with two goals on his U23 debut against rivals Liverpool on January 30 and was followed up by another eye-catching display as Diallo scored again and registered a hat-trick of assists as United came from behind to beat Blackburn’s U23s 6-4 last Friday.
At age 18 years and 218 days, Diallo would become the 17th-youngest player to make his Manchester United debut if called upon to face the Hammers.
He’s still not available for the cup game, we think. He’s been out on the grass and training, but we’re just going to make a decision. I don’t think he’ll be involved.”
The Norwegian has said on Pogba: “Well, it was an injury. It’ll take a few weeks for it to heal, so he’s just started his recovery, working with the medical staff and we’ll get him back as soon as we can, as safely as we can, because of course Paul’s been very important for us.
