Sunderland striker Fraizer Campbell feels he's a stronger character for his injury problems.

Campbell's England call-up is fitting reward for the hard work put in by a player who has scored twice in five games since returning from TWO career-threatening injuries.

"I'd like to think everything I have been through has made me more mature," the ex-Manchester United man says.

"It makes you appreciate it more and realise how quickly things can change. Even four months ago, if you'd have said I would be called up by England I would have just laughed at you.

"You just have to do your best every day and see what happens."
