Football is increasingly a young man's game.
Players now make the breakthrough in their mid-teens as opposed to mid-twenties. The game has become quicker and more physical, and youthful athleticism is in vogue.
However, some warriors remain resistant to the passage of time. These are the players who fight on, defying the creaks and aches to stay at the top of their game.
There is no player in this list below the age of 34. They may not be able to play every minute of every game, but when called upon they never let their side down.
