Wigan Athletic boss Roberto Martinez is convinced Charles N'Zogbia can be a worldbeater.

The young French winger arrived earlier this year from Newcastle United.

Martinez said: "He's an exceptional talent and we are trying to get someone with that talent enjoying their football.

"He's going to be a threat and he's been one for the whole campaign.

"We want that to continue.

"He's such a talented boy. I haven't seen him low in confidence or without arrogance, which you need.

"He wanted to be the best player at the club - and that's a great approach."
