Chelsea legend Frank Lampard rapped Tiemoue Bakayoko for his performance on their draw at Liverpool.
Lampard says the midfielder's defensive game wasn't good enough at Anfield.
He said after the 1-1 result: "When you are a Chelsea midfielder, you play in Liverpool, you must understand that you can not have the ball all the game.
"Without the ball, you can be close to the opponent and squeeze it. In this situation, you help your teammates, make the pass more difficult for the opponent - and he did not do it. He was too slow, he let the opponents raise their heads and play where they wanted. He will have to realize very quickly that he has to go to the next level."
