Diame scored his first goal in English football with a screamer at the Stadium of Light but Kenwyne Jones managed to rescue Sunderland a 1-1 draw in Saturday's Premier League encounter. But Martinez felt the game was a significant milestone for his young French midfielder and has backed the 22-year-old to play a pivotal role in the Lactics' bid for survival which sees them play Stoke, Bolton and Tottenham in successive home fixtures. "The Premier League, in that area, is full of athletes and the tempo is high and Momo has picked up that quick and it has been a pleasure to watch," the Wigan boss said of the 22-year-old. "Now he has scored his first goal and he is slowly fulfilling his potential and is peaking and that is a great positive but he is still a young man and there is more to come." Victor Moses is the latest talent to come to Wigan's doors and Martinez has urged for patience from the Latics supporters as the teenager adjusts to life in England's top tier. "We have to allow Victor to feel himself around the place and remember he is a very young man," added the former Swansea tactician of Moses, who moved to the DW Stadium from Crystal Palace on transfer deadline day. "When you rely on your physicality (and) when you step up a division - especially from the Championship to the Premier League - the gap is huge and it can maybe take longer than expected. "Victor relies on his talent - he is a very skilful footballer - and its going to be just a matter of time before he feels himself on the pitch."
