Boselli shone in their Capital One Cup victory over Nottingham Forest last week.
â€śWe are very, very exited about Mauro,â€ť Martinez said. â€śHe had a difficult period in the previous two seasons but mentally heâ€™s come back really refreshed and I think his experience in Argentina has helped him to be desperate to come here and be successful.
â€śA typical goal-scorer needs to get an advantage into a defender and probably what Mauro does really well in that box is he comes alive.
â€śHe sees that space and, obviously, you need good service. But you always need goalscorers and a goalscorer is precious. I think heâ€™s happier now than heâ€™s ever been in the previous pre-seasons.
â€śI see him now with a bit of light in his eyes.
â€śHeâ€™s desperate to work hard for the team and have an opportunity in the league.â€ť
