"I think I've got Harry Redknapp to thank a lot for my performances since I came to this club," he said.
"I say that a little sarcastically because he treated me like a mug for 18 months and it certainly taught me not to take things for granted; that when you get another opportunity you've got to make the most of it.
"You get frustrated and your confidence dips when you're in that situation, but if you look at my stats in terms of the amount of games I've played and at the level I've played them, I think it shows I can do a job.
"I'm 28 now so I'm not past my best. I'm feeling confident again because the manager's supported me and that's 50% of the battle really."
