Swansea defender Ashley Williams admits he is facing up to life without Roberto Martinez.

Martinez is believed to be in talks with Wigan - where he played for six years - about taking over from Steve Bruce, who was confirmed as Sunderland's new boss on Wednesday.

Williams does not want to see the Spaniard quit the Liberty Stadium, but said: "Nobody wants the gaffer to leave, we are all his players and he brought most of us to the club. He has done a lot for us all, made us better players, and we all owe him a lot. If he goes then I don't know what will happen to the team. But if he goes and progresses his own career then I can only be happy for him."

He added: "He signed me for Swansea from Stockport and has played me all season in the Championship. That is what I wanted and he has given me the chance to advance my career.

"But if he can now further his career in a higher league then I can only be happy for him.

"You do get used to managers coming and going, it does not seem that anyone stays around for more than a couple of years.

"They either get sacked or move on the better things, it is what football is like.

"If a bigger team comes in for you as a player, then you are expected to go. And it is the same for a manager."
