Antonio remains a doubt with the hamstring injury which has kept him out of the last three matches, while Balbuena missed Wednesday’s 1-1 draw against Crystal Palace due to a minor knock.
It was confirmed on Friday that Antonio has signed a new deal until 2023, and Moyes is hoping for more after seeing his forward score eight goals in six games at the end of last season to help the Hammers avoid the drop.
“He’s been really important, certainly since lockdown,” Moyes said. “He’s been instrumental to a lot of goals in how he’s played.
“I’m pleased. It’s good the club had things in control and I’m thrilled we’ve got Mickey sorted. All I need to do now is get him fit and firing and ready to play the way he has in recent weeks.”
