Chelsea are one of three teams, along with Liverpool and Watford, who won all four matches of the new Premier League season.
However, the head coach of the "blue" Maurizio Sarri does not believe that his team is ready to fight for the title.
"Who do I consider the favorite in the fight for the title? Manchester City or Liverpool. We need one more step to be on the same level, "said Sarri.
"I think that this season is not the time for this step, but I hope that it is not so. When you are behind the champion by 30 points, it is very difficult to eliminate such a difference in one season ".
"We need to add in the game, and we can add. Now I believe that we are not doing very well in the defensive phase. In training, I see that the team can add in this component ".
Earlier it was reported that Sarri intends to return Terry to Chelsea.
