PSV Eindhoven defender Jeffrey Bruma has questioned former club Chelsea's transfer policy.

Bruma has warned Blues' exceptional crop of youngsters that few if any of them will make the grade at Stamford Bridge.

He warned: "Every pre-season, players come back from loans with the hope of being in the first-team squad, but you have to realise that you are maybe in fifth spot for your position.

"You have to make a point to play every week to progress - maybe in a different league, or a different country.

"The players who come in for £20million obviously have more chances to play than a young player. But if you go on loan you have to make goals you need to achieve... At Chelsea I've seen players go to League Two clubs and even there stay on the bench."
