I'm not too sure about that, he's not been injured for a good wee while now and instead it's his non stop work and running for 70 minutes that usually leads to him being subbed.
You seen him take off his shirt at the end of games? Body looks not bad to me! Wish I had his upper body build, it's incredible.
Defo, but when you see long distance and endurance athletes, they do not have this type of build.
he has the build of a sprinter and i think time is taking its toll. Of course he works hard during games, alot of players his age do and can still finish games
