Martinez has lined up the powerful prospect as Lee Cattermole's replacement, but he is having a second opinion on a problem that was spotted on his original test.

Both Diame, 22, and Latics are keen to clear up any doubts. He has been at Wigan for a couple of days as he tries to complete his half of a �3.7 million deal from Spanish Second Division side Rayo Vallecano - with team-mate Antonio Amaya also due to join.

Highly-rated Diame is seen as the midfield enforcer to replace Cattermole who re-joined old boss Steve Bruce at Sunderland yesterday in a deal worth �6.5m rising to �8m on appearances.

Martinez is keen to get to the bottom of Diame's problem and get the player signed. If the deal has to be called off he would have to find a 'new Cattermole' in a hurry.

The Wigan chief was willing to sell Cattermole at a healthy profit on the price paid for him when he joined from Middlesbrough a year ago, partly because he had Diame coming in.

Cattermole's tough-tackling style did not entirely fit with Martinez's plans either and he accepted the deal which takes Wigan's sales this year to well over �40 million.

Martinez said: “The fee is a good one, it is far more than the club paid for him last year and the third highest in Wigan's history.

“The initial offer from Sunderland was unacceptable as we said at the time, but they have now matched our valuation.

“The speculation about Lee has refused to go away over the last few weeks and this has been very unsettling for him and for our players.

“It became clear over the past days having spoken to Lee that he wanted to leave and it is very disruptive to the group when a player is clearly unhappy.”
