Arsenal title winner Paul Merson has called on Cristiano Ronaldo to apologise to young Manchester United teammate Anthony Elanga.

United picked up their first victory in three matches on Wednesday night, running out 3-1 winners against Brentford thanks to goals from Elanga, Mason Greenwood and Marcus Rashford.

Yet their triumph did not go without drama, as in the 71st minute Ronaldo reacted negatively to being replaced by Ralf Rangnick.

"Cristiano Ronaldo owes Anthony Elanga a big apology," he wrote in his column for the Daily Star.

"What he did against Brentford spoiled the youngster's big day – and it was so childish.

"The poor kid. He starts his first Premier League game of the season, scores for Manchester United.

"And then Ronaldo gets substituted, strops off and has a hissy fit. As soon as it happened as I said to my mate: 'You watch, you won't even know the kid has scored now.'

"It was unbelievable for someone who's been around the game that long to do that and take the headlines away from Elanga."
