Chelsea ace Nicolas Anelka's move from Arsenal to Real Madrid paid for the club's famous academy.

Gunners boss Arsene Wenger was amazed by the club's ancient training facilities when he first arrived.

Bob Wilson, the Gunners' legendary 1971 Double-winning keeper, explained to The Sun: "I was sitting in an office at the old training ground we used to lease when in walked Arsene.

"I remember him saying 'I do not understand. This is Arsenal? It cannot be Arsenal'.

"First in his sights was a new training ground, purpose-built and paid for in an ingenious way. He bought Anelka from Paris St Germain for £300,000 and sold him to Real Madrid for £23million.

"From that, £12m created the country's best football training facility.

"And with the spare £11m he went out and bought another young French player called Thierry Henry. Some business, some brain."
