Wigan Athletic boss Roberto Martinez says Charles N'Zogbia will prove himself at Aston Villa.

Martinez has backed N'Zogbia to overcome his turbulent start to life at Aston Villa and return to the form that persuaded them to pay Wigan £10m for him.

"With a big transfer fee it happens all the time," said Martinez.

"It is not something strange. What is quite clear is that Charles's quality will flourish and he will settle in."
