Estudiantes striker Mauro Boselli has undergone a Wigan Athletic medical.
The two clubs have still to reach an agreement over the transfer fee but Roberto Martinez wants the highly-rated hitman to pep up his strikeforce.
Talks are set to continue over the deal with Wigan confident of wrapping up his signature, despite competition from other clubs for the Argentina international.
The fee for the former Boca Juniors marksman could rise to above £5million.
