Wigan boss Roberto Martinez is tracking 150 players as he looks to strengthen his squad in the next two transfer windows. General manager John Benson is spending this week watching Honduras - from where the Latics already signed Hendry Thomas and Maynor Figueroa - play Peru.

Martinez is interested in players from both countries but would not confirm one target is Johnny Palacios, the 22-year-old younger brother of former Wigan midfielder Wilson who made a big-money January move to Sunday's opponents Tottenham.

"We really follow many players and we have to do it because we cannot have any errors in our signings," said the Spaniard.

"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."
