His natural athleticism means that he is the perfect physical specimen for a modern day centre midfielder, he's strong, has the stamina to cover ground for 90 minutes and his height means that he is an asset in defensive situations. These are attributes that one is just born with, and its hugely difficult to develop so this alone sets Rodwell aside from many of his young centre midfield contemporaries.
His game as yet in centre midfield is under developed, his position is still lacking and he doesn't seem to have the game intelligence of someone like a Cleverly, possibly this is due to the fact that up until the age of 15/16 he was almost exclusively used as a central defender, so still has a lot to learn in the position which perhaps aside from goalkeeper is most reliant on experience.
Technically however he is extremely sound, well sound enough as a youngster to stand out at every level he has played for England below the senior set up. He is one of the most naturally ambidextrous footballers I have ever seen, and from the perspective of a centre midfielder this skill coupled with his technique gives him so many more passing options, angles and an ability to time a pass that I have rarely seen from someone so young, when he couples these abilities with better game intelligence I see no reason why he will not be able to dictate the tempo of games in a Carrick like manner at the very highest level.
Rodwell is a player who has been a regular starter in team on the fringes of Champions league qualification in the most difficult position on the pitch since the age of 17, and as things stand is still only 20. If we look at the best centre midfielders of the last generation, very few of them had as much experience at the level Rodwell has had by this age, or in my opinion looked as convincing a talent.
