Jose Mourinho has admitted that he does not believe this Chelsea team are good enough to dominate the Premier League this season.
Chelsea lost 1-0 to Everton on Saturday evening, making it the worst start to a Premier League campaign in the Roman Abramovich era.
It is a stark contrast to the Chelsea team of 2004, who swept aside the competition to set a new points record of 95.
In that season, the Stamford Bridge outfit lost just one game on their way to a title in Mourinho's debut season in the Premier League.
However, the Portuguese manager has admitted that this Chelsea team is unlikely to repeat that feat 10 years on.
"No, it is not 2004 all over again," he is quoted by the Daily Mirror.
"Then we lost against Manchester City in October - our only defeat. But that is not the point. We are not unbeatable. This is a different team.
"I came here to work - I don't say peacefully because I am the first one that does not like to work peacefully - but to work with time, to develop the players and play the best they and we can.
"We have to be effective, be adult and not naive. That is what we have to work on. We have to transform the beautiful football we played into goals.
Although keen to dampen expectation, Mourinho did admit that this team is ready to fight all the way for the title and insist the poor start has been down to a tough set of opening fixtures.
"We are not a club who will accept in a cool way that things will come," he added. "We're going to chase it.
"The beginning of the season was hard. Away against Manchester United, away in the Super Cup against Bayern, and away against Everton.
"But Saturday was the story of a team with 21 shots that couldn't score a goal. That is the beauty of football."
