Didier Drogba says he is in confident mood as Chelsea prepare for a potentially tough test against Manchester City.
After disposing of West Brom, Wigan, Stoke, West Ham and Blackpool with a glut of goals, Chelsea face a more realistic assessment of their title credentials when they head to Eastlands on Saturday.
However, Chelsea won six out of six against Manchester United, Arsenal and Liverpool last season, and Drogba is in confident mood.
Speaking at the London Soccer Dome, he told the Daily Express: "I don't think we have had an easy start. People say that because we won all our games, but those games were not easy. At Wigan we struggled in the first half but managed to turn it around.
"City will be a good test to see if we can deal with better opposition. After that it is Arsenal - another big one - so it's a crucial period.
"It's good that we have already got a four-point lead. It will give us a little advantage, but we have to win these games. We will come out to try and win. Let's see what happens.
"We won every game against the big teams last year. It made the difference. When you play those teams, the most important thing is not to lose, and try to win the other games. Last year we won them, and that allowed us to make a few mistakes in other games.
"It's true City were a problem for us last year - they beat us twice. They might be another problem for us this time, but if we win the league at the end, I don't mind."
Drogba is hungry for more goals after Chelsea accumulated an impressive 21 goals in five games.
Drogba said: "In the six years I have been here, this is the first time really that we all want to just be on the pitch. We all want to play - because we are having fun.
"I don't know if it will be the same if it becomes difficult to win games, but this start to the season is very, very interesting. To keep it this way until the end won't be possible, but the spirit is here, and with that you can go far.
"What I like is the fact that the goals are coming from every area of the team. We don't worry about teams anymore. We are playing with freedom. It is a joy to play with his team right now."
