New Celtic boss Tony Mowbray admits his relationship with West Brom chairman Jeremy Peace became strained last season.

He said: "While I have huge respect for the chairman at West Bromwich Albion, the way he runs his club, there were one or two instances that left me with the feeling that, if the right opportunity came along it was something I needed to explore.

"At the level we were working at, in the Premier League, the relationship between the chairman and manager can become strained, particularly when you are in the predicament we were in. As the Premier League season unfolds the true personalities of people come out, I think."
