Chelsea hero Michael Essien is excited watching manager Maurizio Sarri's team this season.
However, he believes the real reason behind their success is the quality in the squad.
Essien told Mirror: “Sarri came in with a different system but the most important thing is the players that he has got. I think they are the players for any system.
“The 4-3-3 is working really well for them at the moment and they have to keep going like that and win something.
“Getting a new manager is always difficult but it seems like that players are warming to what he is doing and they are on the right path, so hopefully they can do something this year."
