"I see this as probably one of the biggest achievements of my career. I'm nearly 34 and so to earn this contract is massive for me," he has siad.
"I feel very happy with how I've done as a player in my career and pleased with what I've achieved but this is another great new challenge.
"I've had the privilege of playing in the Premier League twice before with Sunderland and with Wolves and am really looking forward to going back in there again.
"There have certainly been a couple of times when people might have wondered whether I'd still be involved at Wolves.
"A couple of seasons ago I went off to Stoke on loan and and then last year unfortunately I missed out for a long time through injury and then not getting back in the team.
"Both times I've come back though I've managed to win my place back which has been great. Obviously I don't know what's going to happen next season but I'm just happy to be here and fighting for a place.
"I know it's going to be tough for me again and I know there will be new defenders brought to the club but it's never been any different.
"It's the Premier League and it's a difficult challenge but I know what I'm signing up for."
