West Ham assistant manager Billy McKinlay has claimed that new signing Thilo Kehrer may even play for the club on Thursday in the Europa Conference League play-offs.
The Hammers are set to take on Viborg as they bid to reach the group stages of the competition.
They have secured the German international Kehrer from Paris Saint-Germain on a four-year contract.
"We'll see how he settles in, get a bit of feedback from him and see how he feels over the next 24 hours," said McKinlay at Wednesday's pre-match press conference.
"He trained a little bit with us this morning."
On where Kehrer would play, he added: "He's played predominately for the national team at left-back and centre-back for PSG last season, so we feel we have a really good acquisition for the squad.
"He will be able to add to us in a number of areas."
