West Ham manager David Moyes hopes to have summer signing Nayef Aguerd in his squad for Thursday's Europa Conference League game against Silkeborg.
Morocco defender Aguerd, who joined the Hammers from Rennes for £30m in June, has not featured since injuring his ankle in pre-season.
Moyes said the 26-year-old is not yet ready to play in the Premier League but could feature in Europe.
"I see Nayef hopefully giving us something we've not had," said Moyes.
"He's not in contention for Sunday [against Manchester United] but we're hoping to have him in the squad tomorrow, one way or another," he added.
