Cristiano Ronaldo is a doubt for United's match against West Ham due to a neck complaint.

Having missed two matches with a hip flexor issue, the 36-year-old made his return in Wednesday’s 3-1 win at Brentford.

Ronaldo made headlines with his reaction to be taken off in the second half by interim boss Ralf Rangnick, who has revealed the forward might be absent entirely on Saturday.

"Cristiano is a question mark because he has a problem with his neck," he told MUTV.

"He received treatment yesterday for two to three hours and we will have to wait to see how he feels today.

"Edi (Edinson Cavani) hasn’t been training with the team yet and will hopefully resume training today and then we’ll take the final decision after the training session today, (around) if he will be available for the game tomorrow."
