Manager Roberto Martinez insists Antolin Alcaraz is contracted to Wigan and will not be joining anyone else.
The Latics announced they had agreed terms to sign Alcaraz before he travelled to the World Cup with Paraguay, but quotes have since been attributed to the defender suggesting he believed the deal to be only preliminary.
"Antolin signed a contract with Wigan Athletic, he's a Wigan Athletic player and that's the end of it as far as I'm concerned," Martinez told the Wigan Evening Post.
"If he had wanted to wait until after the World Cup, he wouldn't have signed his contract. He would have waited.
"I do know that he's eager to get things sorted out and arrive here in Wigan.
"Antolin had an interview back in his homeland, and the translation of that didn't really reflect what he was talking about or what he meant.
"What he said in the interview was that he doesn't know for sure where he is going to be until he receives his work permit.
"We need to make sure we get everything sorted now - and we will do."
