Wigan manager Robert Martinez has confirmed the club are hopeful of completing a deal for Sporting Kansas City's Roger Espinoza.
Espinoza, 26, can play in either defence or midfield and has long been linked with a move to the DW Stadium.
"We're working really hard to try to make it happen," said Martinez.
"We're looking forward to seeing if we can get that one done successfully. Until 1 January it's something we can't do any more than wait on."
Espinoza impressed at this summer's Olympics with Honduras, especially in the 3-2 quarter-final defeat by Brazil and his contract with the Major League Soccer club expires at the end of the month.
Martinez said: "There are a few steps - there is the work permit, there are certain aspects we need to fulfil in the paperwork - but Roger is a player that we've been following for a long, long time."
