Cristiano Ronaldo returns to Manchester United a completely different player than when he first arrived.
When the Portuguese winger joined from Sporting Lisbon in 2003, he had plenty of raw potential, but still had everything to prove as an 18-year-old.
It wasn't a straightforward journey, without any bumps in the road, he had to fight and claw for every inch in what was an experienced Man Utd dressing room.
It's claimed that Ronaldo was 'bullied' by the senior players at the club early on, according to former teammate Mads Timm.
But Ronaldo being Ronaldo, he didn't back down and ‘took the fight against the hierarchy’ - as in the seasoned veterans inside the dressing room.

Timm wrote in his autobiography which was sampled by The Sun earlier this year: "He was quite extraordinary as a footballer, and as a person.
"Like me, he was bullied when he came to the club.
"With his hair – which he soon got clipped – and with his almost acrobatic attempt to impress the coaches.
"He could stand and do 10-15 stepovers before he tried to dribble past the opponent.
"‘Pass now, just pass, dammit,’ shouted Gary Neville and Ole Gunnar Solskjaer constantly to him when we had reserve team matches together.
"The special thing about Cristiano Ronaldo was that he immediately took the fight against the hierarchy. And he won it.
"He was completely indifferent to the rest of his teammates. He gave no room for others. It was me, me, me. Cristiano Ronaldo. CR7."
As Ronaldo prepares for his second stint at United, he now commands the respect of every player inside the changing room for what he's achieved in the game since he's left.
Ronaldo's playing style will also be drastically different too as he has transitioned from an electric winger into a clinical forward.
But Harry Redknapp reckons he can still be as effective despite being at the tail end of his career.
He said: “I don’t think we’ll see the Ronaldo of old, you’ll see him passing more, rather than speeding at defenders.
“And he’s just got that knack of being in the right place at the right time.
“He will be Ole Gunnar Solskjaer’s biggest ally, because he shows everyone else how to do things, how he works, how to live their lives.
“Carlo Ancelotti told that when he managed him at Real Madrid, Ronnie was always first in and last out at training. Not now and then, but every single day.
“Mason Greenwood, 19, Jadon Sancho, 21, and 23-year-old Marcus Rashford . . . all those young players at United will learn so much from him.
“All the Academy kids, they should be watching him and soaking up every bit of knowledge they can.”
