Chelsea boss Frank Lampard insists his system doesn't need a No10.

The under-pressure Chelsea boss admitted he is aware of question marks around his set-up, with some calls to find space for a natural central playmaker.

But the former Chelsea and England midfielder insisted that, at its best, his Blues blueprint can harness the greatest potency from his myriad attacking talents.

“I've heard some people talk about the system with two eights as though they have to run in straight lines up and down the pitch," said Lampard.

“It doesn't have to be that way when you have players with different qualities like Mason Mount, Kai Havertz, Mateo Kovacic, N'Golo Kante.

“These players play in different ways and arrive between the lines and sometimes into the area inhabited by an orthodox number 10.

“And that can be more dangerous than a number 10 that just stands there all day. They can be, for me, more dangerous, but those are the things that need time."
