Wigan boss Roberto Martinez believes the disruptive influence of agents means there should be no competitive fixtures played during transfer windows.
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."
