Rojo? Mourinho? Jones? Young?
you're missing my point. shit players like that showcase that footballers will never really be short of a job opportunity, particularly if you're in any way 'slightly above average'. so the risk of running down your contract really lies with injury, and even then, teams would likely take a punt once you'd recovered if they could get you on a free.
it's basically taking the money away from the clubs (the selling fee) and putting it in your own pocket.
