Wigan manager Roberto Martinez is tracking upwards of 150 players as he looks to strengthen his squad in the next two transfer windows.
One area of his search is concentrated on South America with general manager John Benson spending this week watching Honduras - from where the Latics already signed Hendry Thomas and Maynor Figueroa - play Peru.
"We really follow many players and we have to do it because we cannot have any errors in our signings," said Martinez.
"In every window we have to improve the squad and help the players we have here to become a stronger team.
"It is too early to talk about names but we are working hard and have been since the summer.
"We need to get the right characters and personalities and they have to bring something different to the squad."
Martinez is looking to bring in three players in January, as well as tie up some free transfers for the summer, but will not buy just for the sake of it.
Another factor to take into consideration is whether he will lose any of his squad in just over a month's time with former Wigan boss Steve Bruce expected to come in with a bid to take left-back Figueroa to Sunderland.
