Chelsea boss Jose Mourinho has warned their successful youth team they have it all to prove at senior level.

Mourinho has warned the burgeoning stars that the pressure at Stamford Bridge is to collect trophies, not produce players.

"If they're good enough and they're ready then yes," Mourinho said when asked if having a core of home-grown talent was a target. "It's important, but this club is a very demanding club. It's a club where it's not easy to play football. The level people demand is high, the pressure is big.

"It's not the same to play in a club where people just accept a so-so performance, or people accept a so-so result. Or accept that you finish 5th, 6th, 7th or 8th.

"This is not the best habitat for a young player to be developed. For a player to play in the Chelsea first team the player must be ready. There is no space with this level of demand, responsibility and pressure. There is no space to play a player who is not ready."
