Chelsea midfielder Jorginho admits they need to cut out the errors after their Champions League thriller with Ajax.

Frank Lampard's side came from 4-1 down to draw 4-4 with the Dutch champions, who had two men sent off in a bizarre second half incident that also saw the Blues awarded a penalty.

"We didn't win and we should have done," said Jorginho. "In this situation when you are with two more players, I think we could win and we should.

"[We have learnt] that we cannot make mistakes, [at] this level of football you can't. Every single mistake we can lose the game. We could play with more calm when we had two more players, not go for goals straight away, pass a little bit more to find space. I think we learnt that we can improve from this game.

"I think the most important thing is we didn't give up. When it was 4-1, it is hard to believe and we did. It is so important for us."
