Players develop strength and fitness levels with age. He's only just 21 so probably has another 4 yrs developing to do in that regard.
I'm more concerned about how he'll develop as a player. He'll only improve playing against (and with) top players and I don't think anyone is going to take that risk with him.
If we can get somebody in Germany or France to take him on loan at the moment I'd bite their hands off. Personally I'd like to see him played a bit deeper but with license to push on. I think he's a player who prefers to play with the game in front of him.
And some players just don't want to push themselves that extra bit mate or don't believe they need too.
I don't ever envisage a time in the future where you'd see dowell putting in a huge amount of running in a game for example.
Ultimately, he's a player who twenty odd years ago could have easily made it to the top, hell sheedy for us didn't exactly cover much ground, but in the modern game with fitness levels so high everywhere just don't see that type making it now.
Just think the lads grew up to this age able to get by on being far more talented than most others so never added those parts needed to make it, and can't think of many at his age who suddenly changed mentality on how they play the game which lets face it he'd have to do a complete u turn on
