Wigan Athletic boss Roberto Martinez is calm over Franco di Santo's contract future.

Despite all the work Martinez has done on Di Santo, he is relaxed about the prospect of losing the South American on a free when his contract expires in the summer.

"That does not worry me," he said. "I will never put a gun to a player's head to get him to sign a contract.

"At the end of the season, whatever will happen, will happen and I'm not worried about it."
