David Moyes has confirmed Brazil international Lucas Paqueta underwent a medical at West Ham on Sunday ahead of a proposed transfer.
The 25-year-old is expected to seal a big-money move to Premier League club Lyon early next week.
Moyes, speaking after his side’s 1-0 win at Aston Villa, revealed: “I understand he also had a medical today.
“I can’t confirm if it’s all good or all bad. I obviously really hope that happens because I think he’s a great player.
“He can add something for us and he’s another exciting player.”
Paqueta would be West Ham’s eighth addition this summer, following Nayef Aguerd, Alphonse Areola, Flynn Downes, Gianluca Scamacca, Maxwel Cornet, Thilo Kehrer and Emerson Palmieri.
“We brought in several players and a lot of them are internationals,” added Moyes.
“If we bring in a Brazil international as well, it’s been a tough window, but trying to add something at a level that we think can probably keep us up there, that’s what we tried to do.
“And I have to say I’m grateful to the club and the board for trying to give us our best.”
