Kieron Dyer has revealed he still feels guilty for the way he behaved earlier on in his Newcastle career under former manager Sir Bobby Robson.
The veteran manager was sacked after a poor start to the 2004-2005 season and it followed a falling out with Dyer over his public refusal to play on the right-hand side of midfield.
Dyer has recently declared that he does not enjoy playing in this position, but confesses his behaviour was 'naive' and 'stupid'.
"I still feel incredibly guilty about that," Dyer told the Daily Mirror.
"The players at Newcastle used to call me 'Bobby's son' because he would give me special treatment and the odd day off to go back home to Ipswich and I let him down massively.
"He was sacked soon after which made it all a hundred times worse. I should never have done that. I was just young and naive and stupid.
"It's something I will have to live with for the rest of my life and I'm thankful that when I rang him after he was fired he accepted my apology."
