Martinez this week described speculation linking Maynor Figueroa with a move to Sunderland as "disgusting" after he felt the talk had affected his player's performance in the 2-1 defeat at Blackburn on Wednesday night.

The Spaniard, who is still weighing up whether or not to make a complaint to the Premier League about the matter, thinks the January schedule is too hectic for any interference and has called upon the authorities to keep football and transfer negotiations separate from one another.

"In a way you will never stop them (agents) and I'm not going to be someone who tries to change that," Martinez said.

"My concern is that we allow these situations to happen in the middle of very important games.

"In January you are involved in the FA Cup, you are involved in the league. It is a key moment in the season and all this transfer speculation and the way that the agents deal with it, it really affects players' careers.

"So that is something for the authorities to look into and see if we need that sort of unhealthy part, of people surrounding the game.

"I think its quite clear we should look into it and if we need to have a window I don't think we should have any competitive fixtures in that period."

Asked if he intended to proceed with a complaint over Figueroa, Martinez said: "We will look into it and obviously it's very difficult to prove these sorts of situations. If we do anything, we will let all the fans know."

Reports prior to the Blackburn match suggested Figueroa had threatened to go on strike in an attempt to engineer a move away from the DW Stadium and bring about a reunion with Sunderland boss Steve Bruce, who signed him for Wigan in 2008.

But Martinez stressed he had no problem with the player himself and reaffirmed his determination to hold on to the 26-year-old Honduras international.

"I've heard many, many stories and none of them are true," Martinez said.

"Maybe with what people want Maynor to do, they have to realise that he has pride in his profession and too much respect for Wigan Athletic and all his team-mates.

"All the stories of Maynor doing something wrong, I can guarantee - not just now - they will never be true.

"The players, the individuals, the best performers that we have at the club - it is great to see that other clubs are interested in them because it shows how well we are doing and that must be a sign that we are doing something right.

"But it is important that everything has to be right for Wigan Athletic and the fans can be quite relaxed about it that that is going to be the case.

"Maynor is going nowhere and we hope that he enjoys, with no distractions, the rest of the season and that he goes to the World Cup and makes everyone proud."
