Chelsea boss Jose Mourinho insists Manchester City's impressive new training complex won't guarantee success.

City opened their new £200million headquarters on Monday with the view to becoming a factory for bringing through talent. It eclipses the £30m Chelsea spent in 2005 on their academy.

Mourinho said: "It depends on the talent you have. Every manager in the world wants to bring young people up. Sometimes you have it. Sometimes you don't. I can compare my first spell here to now, and now the quality of the young players is clearly better.

"I'm not saying they're ready, but the quality is much better.

"Go to other clubs, it's clear it's not easy to bring kids from the youth competitions to the top level, but every one has the same feeling. We want to do it."
