Real Madrid captain Raul admits he could quit the game in two years' time.
The 33 year-old striker signed a 'lifetime' contract earlier this season, but says he can't see himself playing beyond 2011.
Raul said: "It is a difficult situation because in reality you should always leave when you are on top.
"However, when you're playing well you start wondering if you really need to ever leave football. At the moment I am thinking of leaving football in 2011."
