Chelsea midfielder Nemanja Matic says they haven't missed Frank Lampard this season.
Lampard has been superb for Manchester City over the past fortnight.
"Yes. Sometimes you have a player (like Frank) who plays very good and can score every game," Matic told the London Evening Standard.
"But in this moment Chelsea have different players scoring every match.
"Of course Diego has been doing very well and scored eight in six League games - that is not easy to do. But I think as a team we are perfect.
"It's important to have a player in form like Diego that can score in every game if possible. But we have already had 11 players scoring goals and that's good for team spirit and for the club.
"It shows we have a lot of quality in the team and every player can be decisive, in every moment.
"As a group we are really strong. Chelsea plays like one. Everything is going well for us."
