Former Nottingham Forest defender Kelvin Wilson is delighted to be completing his Bosman move to Celtic. He admits playing the second-half of the season with a pre-contract was tough.

Wilson, 25, said: "When you've signed a pre-contract your mind and heart is with the other team.

"I tried to make that clear to Forest. I'm a Nottingham boy, a Forest fan, and I wanted them to do well but it was time for me to move on.

"I didn't go to Forest and ask them to let me leave. I left it to the two clubs because I knew I was coming in the summer.

"I'd have loved to have been a part of it but things don't always go to plan.

"I was carrying a few niggles at Forest and the team was doing really well. There was no point risking the injuries and I'd signed the pre-contract.

"For both parties it was right for me not to play. I got on well with Billy all the way through.

"He signed me at Preston and there's never been a problem. He never had a go at me and there were no arguments. He wished me well when I signed the pre-contract.

"Without him and Colin Calderwood, who gave me that chance to get away from Preston and play football at Forest again, maybe I wouldn't be sitting here.

"I said I'd only leave Forest to go to a bigger club and in joining Celtic that's what I've done."
