Wigan Athletic chairman Dave Whelan says new Everton boss Roberto Martinez is free to return to the DW to sign his old players.

Whelan has a very close relationship with Martinez but insists he was not interested in negotiating any 'strings-attached' deal ahead of his switch to Everton.

"There is no agreement. It is unfair and I don't believe in anything like that," he told Press Association Sport.

"If Everton want to sign any of our players for the right amount of money we will consider it."
