Manchester United attacker Anthony Martial is facing an injury scan today after hobbling off during their win at Everton.
Martial was forced off early at Goodison Park.
United manager Erik ten Hag said: "We have to wait. I can't diagnose.
"I don't think it's that big a problem. He had an assist for the first goal. I'm happy with that.
"It was a setback for the team but Ronaldo came in and made the winning goal, I'm happy with that."
