Wigan Athletic signing Gary Caldwell believes he was sold behind the back of Celtic manager Tony Mowbray.
He insisted Mogga wanted to keep him - with Celts chief executive Peter Lawwell and majority shareholder Dermot Desmond the men behind his departure.
Stopper Caldwell told the Scottish Sun: "You have to ask Peter and Dermot if they underestimated me as a footballer.
"They judged me and their judgement was a little bit off from mine.
"I have no regrets - I had three and a half years there and they were great for me. Hopefully I was good for them.
"But the boss had one opinion and the club had a different one. I think the club won in the end."
