Chelsea boss Maurizio Sarri admits he may persist with Eden Hazard as a false number nine.
Hazard scored again for victory at Brighton on Sunday.
He did not name a traditional striker in his starting XI for the second game in a row, with Hazard deployed as a false nine at the Amex Stadium.
"In Napoli I was used to playing with a solution like this (without a traditional number nine)," Sarri said.
“This is very important for us, to have continuity or it is impossible to stay in the top four.
"It is important to stay very close to the top four. I want to see continuity from the mental point of view and the tactical point of view.
“We need to get 80 points to get into the top four."
