Wigan boss Roberto Martinez has backed flop striker Mauro Boselli to make a big impact at the DW Stadium this season.

The Argentinian reportedly cost the Latics more than £6million when he arrived from Estudiantes in the summer of 2010 but he has made only 14 appearances for the club, with his two goals both coming in the League Cup.

"Mauro's attitude has been tremendous. He wants to play games, he wants to be ready to help the team, and that's a real sign of maturity. Over the course of the season, he's going to be very important," said Martinez.
