I think Petrov would be a great player to play the odd game, or bring on with 15 minutes to go if we're winning and calm things down. He's at a stage in his career where he should no longer be the main man, at least if he wants to continue playing at this level. It must be difficult for players to accept that after a career where they have had a higher profile. If he can accept that mentally, he'd be a tremendous asset to have.
