Chelsea manager Jose Mourinho has highlighted those who make it difficult for young players to come through the ranks.

The Blues boss is set to unleash Ruben Loftus-Cheek, Izzy Brown and possibly Nathan Ake in Monday night's clash with West Bromwich Albion but the Portuguese says their development has not been without its glitches from outside influences.

"The most difficult thing in bringing a teenage player through? In modern football, the agents and the parents," said Mourinho.

"When the players are almost there and in the process of being almost there, they (parents and agents) think they are already there.

"They make the players think they have arrived when they haven't. They think about money before the career starts, and everything gets very confused.

"That doesn't help the players. They need stability."

He added: "But to be in a big team and reach the level to be playing regularly for the first team, you need time and stability. We try to give that to our boys."
