He told the Sunday Mail: “The decision to leave was made for me. Celtic left me with no option but to go elsewhere. The whole situation was well documented.
“Things have not gone as well as I would have liked at Wolves but that’s the way football can be.
“I’ve had two serious injuries including a cruciate one I got in a training ground accident when I fell awkwardly.
“I’m not in the team since McCarthy took over from Glenn Hoddle. That’s frustrating because I’m back to full fitness and have been for a month.
“But even taking all this into account I do not regret the decision I made. It would have been 10 times worse for me if I’d stayed at Celtic.
“I look at Alan Thompson’s situation now. He has been a top servant to the club, scored great goals and played a part in some of the best results in their history. But he is right out of the picture.
“Perhaps I would have ended up in the same situation – that’s the way I look at it.
“The Celtic fans were great to me when I was there and I received letters of support from them after I left.
“That meant a lot.”
