Edinson Cavani will miss the game against the Hammers.
The Uruguayan forward continues to recover from the knock he sustained in training and will miss Sunday’s trip to the capital where they face Hammers.
Manchester United will be looking to bounce back from their humiliating away defeat against the Young Boys.
“Edinson hopefully will start training with us after the weekend,” Ole added. “Hopefully, maybe Monday.
“Maybe he’ll be involved on Wednesday because he had a fantastic season last season.
“The impact he made towards the end of it when he got his fitness… because he struggled early on with fitness, he struggled with niggles.
“We feel now to get the best out of Edinson this season we need him to have 100 per cent fit and not pushing. We’ve got a strong squad that will cope with having to let players heal and don’t risk any further injuries.
“I see Edinson having a massive impact because he’s that type of personality and a player. He’s a top professional and he can’t wait to get back on. He’s working really hard to get back on the pitch.”
