And the 28-year-old believes the Clarets can defy the odds to maintain their Premier League status after the club enjoyed a fleeting existence in the division in 2009-10.

"It's great to be a part of it, and I'm looking forward to hopefully being a bit part of it going forward.
"We will set our stall out [to be] ambitious again and the aim is to stay in the Premier League and then kick on from there.
"I think I'm the eternal optimist but you never know what you can achieve and I think I've been in the game long enough to know what is around the corner if you do things properly.
"If you do that as individuals and a collective then you give yourself a great chance and that will certainly be the motto from me again.
"I feel that personally I have got more to come and I'm really excited to show that here."
