Chelsea boss Jose Mourinho says it's impossible to split Liverpool skipper Steven Gerrard and Frank Lampard.

Over the years there has been a great debate as to who is the better play, Gerrard or Lampard, now of Manchester City.

"I always thought that both were the best two No 8s in Europe," said Mourinho.

"From 2004 to…. I will not say until 2014 but until 2012 they were the best two No 8s.

"In my opinion and my vision with them you don't play a No 10 you play with one No 6 and give the freedom to the two No 8s because they score more goals than any No 10.

"Lampard with 30 goals a season and Gerrard with 25, they score more goals together than the No 10 and the striker."
