Mason Mount made his Premier League debut for Chelsea against Manchester United back in 2019 but the midfielder has undergone quite the transformation since then.
Having been unable to agree a new contract at Chelsea, the England international is set to sign for United in a £60 million switch.
United will pay £55 million for Mount, with a potential £5 million owed to Chelsea in add-ons should the 24-year-old help his new club win the Premier League or Champions League multiple times.
Mount is set to sign a five-year contract which includes the option of an extra year and will be one of United's top earners on a basic £250,000-a-week deal.

He joined Chelsea at the age of four and went on to make his first appearance at Old Trafford against his new employers in a 4-0 defeat.
But Mount's physical appearance has changed dramatically since 2019. Despite his technical ability, many felt as though the former Derby County and Vitesse loanee would need to improve his slight, scrawny build so he could cope with the demands of top-level men's football.
And he has done exactly that, putting in the work and bulking up considerably to build strength and ensure he is not easily knocked off the ball.

His transformation genuinely looks like something you'd find at Bayern Munich, who have seen many of their players become absolutely jacked in recent years.
Mount has his own fitness coach and revealed last year that he had been placing a focus on improving his physique - but making sure it didn't affect other parts of his game.

"I think it's just natural, as soon as you get older you start filling out a bit more," Mount told Sky Sports News.
"Over the last three years, I've gained a bit more structure. It's something I work on.
"You want to be someone that's able to put yourself about a bit as a midfielder but people are picking up on it. It's not done yet, it's a long journey and it's only the start of it.

"You want to work at that side but you've still got to be sharp and agile, and doing the stuff I do, pressing and running forward. You've got to be able to do that as well, so it comes hand in hand."
