The Blues have made a surprisingly positive start to the Premier League season despite finishing in fifth spot in the English top flight last term.
Chelsea FC appointed Maurizio Sarri as Antonio Conte’s replacement in the summer and the former Napoli manager has revolutionised their style of play.
Sarri has brought an attacking brand of football to the west London side and has managed to get the best out of his playmakers such as Eden Hazard and Ross Barkley.
Chelsea FC won eight times and drew four games in their opening 12 Premier League fixtures of the season before November’s international break.
The Blues were 3-2 winners against Arsenal in their second fixture of the campaign, while Chelsea FC earned point in draws with Liverpool FC and Manchester United.
Sarri’s side will undergo a stern examination of their title credentials on 8 December when the Blues welcome defending champions and current leaders Manchester City to Stamford Bridge.
Liverpool FC have been billed as the Citizens’ closest challengers in the current campaign, but former Chelsea FC striker Hasselbaink believes Sarri’s side will run Manchester City closest.
“I think Chelsea are still a little behind Man City. City have so much strength in depth and the Champions League is not affecting them,” said Hasselbaink, speaking exclusively to 888sport.
“But if Chelsea can keep on improving and don’t allow the gap to become bigger than it is now then you never know.
“With Liverpool they are not as fluid as they were. I don’t know if they have enough to keep on challenging City and maybe they’re suffering a bit from coming out of a big group in the Champions League.”
Chelsea FC won the Premier League title in 2015 and 2017 under Jose Mourinho and Conte.
