Sky Sports sources understand that Fulham have made a bid for Wigan Athletic striker Hugo Rodallega.
The Colombian is out of contract in the summer and he admitted last week he was looking to leave.
Now Sky Sports understands that Fulham have made an approach and have offered cash plus a player, believed to be Andrew Johnson.
With West Brom and Queens Park Rangers also linked with the 26-year-old a deal before Tuesday's deadline looks a genuine possibility.
And Wigan boss Roberto Martinez has refused to rule out selling Rodallega, saying: "We are in a position where no-one is bigger than the football club.
"Whatever could happen over the next 48 hours will be in the best interest of Wigan.
"Every individual situation is going to be down to that measurement."
However, Martinez stressed that neither Victor Moses or James McCarthy would be allowed to leave.
"Victor Moses is not for sale. He is one of the biggest assets we have at the club," said the Spaniard.
"He is one of the players who represent Wigan [in terms of what the club stands for] as he is young with fantastic potential and has had great development in the last season or so.
"He is not on the market, he is not for sale and that is the end of the matter.
"Victor and James are the two younger players in this football club and it would be wrong for us to sell these assets.
"Obviously with other players, when you get into a position when your contract is short-term with the club it is a completely different situation."
