Martinez hinted Boselli â€“ who scored on his only start this term in the Capital One Cup win at Nottingham Forest â€“ is in line for a recall up front.
â€śWhat happened on Monday will obviously act as a real confidence-booster for Mauro,â€ť Martinez told the Wigan Evening Post.
â€śBut more than that it shows you the kind of attitude he continues to show behind the scenes.
â€śIt would be all too easily for him to be disappointed, but all he is focused on is preparing himself if and when he is called upon.
â€śHe knows he is going to get his chance, and he is determined to work as hard as he can in the meantime.
â€śMauro came and asked me whether he could play in the Under-21s, which is a fantastic sign for me as a manager.â€ť
