Manchester United could be without Cristiano Ronaldo for the Old Trafford fixture with West Ham after he complained of a neck injury after Wednesday's win at Brentford.
Interim manager Ralf Rangnick said Ronaldo needed lengthy treatment on the injury on Thursday and was now a doubt for the crucial Premier League fixture with the Hammers.
Ronaldo was unhappy at being substituted 19 minutes from time in the win over Brentford, but didn't show any signs of injury and Rangnick hasn't mentioned it as a reason for his replacement either after that game or in his press conference to preview the West Ham fixture earlier.
