Arsenal's departing goalkeeper Jens Lehmann says England's goalkeepers are struggling because they're too thick!

"Sometimes goalkeepers over here are not going to school long enough," he told the Daily Mail.

"When you are a goalkeeper you must hold your concentration level very high throughout 90 minutes, sometimes 120, sometimes 150. The best way to learn that is at school with academic focus on tasks. When you leave school at 16 you don't have it, you lose it.

"That's probably why the foreign goalkeepers are coming over. I know some of them and they are bright people, like Petr Cech and Edwin van der Sar."
