Cristiano Ronaldo is a doubt for Man United's clash with West Ham with neck injury

Cristiano Ronaldo has emerged as a fitness doubt for Manchester United's Premier League match against West Ham on Saturday.

The Portuguese forward suffered a neck injury during the 3-1 win at Brentford on Wednesday night, when he was taken off and threw a tantrum at interim manager Ralf Rangnick.

Ronaldo sat on the steps in the away dug-out at the Brentford Community Stadium and was caught by the television cameras asking Rangnick for an explanation as to why he was subbed for Harry Maguire.

The German coach explained afterwards that he wanted to reduce the risk of United throwing away a two-goal lead late on as they did at Aston Villa last weekend.

But Rangnick has revealed that Ronaldo suffered a problem with his neck during the game and received treatment on Thursday for several hours.

'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.'

United could be further depleted for the important top four clash at Old Trafford.

Rangnick will speak to Jadon Sancho to gauge his state of mind after a family funeral this week that caused him to miss the Brentford match.

Defender Victor Lindelof will be with his family after a break in at the Swedish International's home. Aaron Wan-Bissaka, Luke Shaw and Eric Bailly are also ruled out.

Paul Pogba is still not ready to return from his thigh injury and striker Edinson Cavani is another doubt.

Rangnick said: 'Edi 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.'
