Arsenal boss Arsene Wenger says he needs to start focusing more on the talent in Belgium's Jupiler League.

Wenger is becoming increasingly impressed by the quality of player the Belgian championship is producing.

"Belgium produces players. Maybe they are a championship that we give not enough credit. We say: 'OK, he is doing well but he is in Belgium.'

"But you see when they move out. Look at the number of players they have produced recently: [Mousa] Dembélé, [Eden] Hazard, [Axel] Witsel. We don't speak about the guys that we know here like [Thomas] Vermaelen or now [Jan] Vertonghen. Maybe it's a championship that we have to look a little bit deeper in."
