Manchester United defender Rio Ferdinand admits this season's injury-riddled campaign has been the most frustrating of his career.

However, Ferdinand will be fit for tomorrow's final game of the season against Stoke City.

"Disappointing, frustrating, all those kinds of words spell it out for me really," he told the Guardian. "Fingers crossed I'll have an injury-free period now and I can go into the World Cup fairly fresh and be one of the guys with the fresh legs. Last season [and this one] has been the worst injury-prone [time] of my career, really. It took a bit of getting used to."
