Manchester City signing Rodri believes that he is physically prepared for the Premier League.
The shift from La Liga to English football has been difficult for other players in the past.
However, the former Atletico Madrid defensive midfielder insists that he is ready to hit the ground running.
"The only truth was I had a later development," he said to reporters.
"I wasn't developed like my team-mates. It was one or two years later, so I wasn't big and strong when I was 16 or 17 but I decided to move for many other reasons.
"I'm happy for that because maybe I wouldn't be here if I didn't move to Villarreal in that moment.
"Football is changing now. It's getting more physical, of course in the Premier League. It's good for me to have that physique in the position I play.
"One of the things the team can get is more physical. We have lots of players that are great or small. You never know if it's good or bad but having a mix of players is always good.
"You don't win only playing good, you need more things and that's why teams are changing their philosophy. I noticed years ago that I had to become both a defensive and attacking player if I wanted to be good enough to be in Manchester."
