Mexican club Necaxa claim striker Hugo Rodallega is set to join Wigan later this month.
Necaxa have revealed that a deal for the 23-year-old Colombia international has been done, although they refused to disclose any details.
Club spokesman Rosendo Duhart said: "It is a fact. Hugo is joining Wigan on January 15.
"I'm afraid I cannot say much more as the board are in Mexico City at the Mexican Football Federation headquarters because the transfer window is closing, but I was told and I can say the transfer has been set."
Rodallega scored 15 goals in 36 games for Necaxa last year and has previously represented Mexican sides Monterrey and Atlas.
