Following Newcastle's 2-0 FA Cup win at Fulham on Saturday, he told BBC Radio Newcastle: "There's no place I'd rather be. There's been a lot of speculation about me recently but, as always, I'm committed here. 100% committed, as I have been since I first signed."
On the interest from Bayern, he added: "It's over. As I've said before, I'm committed. I've had a nice break with my family and I'm not worrying about anything. I'm committed to the club - they've done a lot for me and I want to give back. I've been quiet but not thrown my toys out of the pram or anything. I'm happy here, like I've always said, and want to give everything for the club."
