Kobbie Mainoo, a starlet for Manchester United, has had a big change to her body in the past few years.

This season, boss Erik ten Hag has slowly brought the 18-year-old junior player into the first team.

Kobbie Mainoo has made it into the first team at Manchester United this season.

During his big year, the young midfielder hasn’t been afraid to put his foot down.

A past coach said that Mainoo, who is shown here playing for the U18s in 2021, used to be a small and “wiry” player.

So much so that some Old Trafford fans have asked Ten Hag to start Mainoo more often, the player has shown maturity and skill beyond his years.

One United fan said, “He’s going straight to the top” after seeing how well he played.

The teen hasn’t looked out of place and already seems like he can handle the physical duties of his job.

.

His strength comes from working out hard and eating well, which has also taken away his “wiry” look.

Mainoo has changed a lot over the years, and people like Cheadle and Steve Vare, who has known him since he was five years old and is in charge of FC Gately’s school, have been shocked by it.

“I went to the Youth Cup final,” he told the Manchester Evening News. He’s almost impossible to recognize.

“Because he’s grown up now and was so little when he was at Cheadle and Gatley.”

“When I first saw him, I thought he was wiry, strong, and quick on his feet.”

He played for Manchester United and helped them win the Youth FA Cup in May 2022. 

“He was one of those players who could push the ball past a player, and he could spring forward like electricity.”

“He’s a big kid now, and I thought he played great in the Youth Cup final against Nottingham Forest.”

“When I make my kids laugh by telling them I coached him, they say, ‘But only for a short time.’”

“Cheadle and Gatley clearly only had a small impact on his growth, and as with everything at the grassroots level, it’s just a base for the kids.”

“But everybody at Cheadle and Gatley is so happy for him, and it’s great to see him doing so well.”

When Mainoo was playing for United, he was at his best.

Paul Scholes, a great Red Devils player, also thinks that his recent play shows that he should stay with the team longer.

“I think Mainoo needs to play for the team,” he said.

“I believe it’s time to give him a chance.

“This back four needs to be looked after. This young boy feels fear more than anyone else.
