Chelsea midfielder Michael Ballack thinks Jose Mourinho's current side need more time before they show the form they are capable of.
The Blues have made a strangely lifeless start to the defence of their Premiership crown although they are still second in the table.
They lost at Middlesbrough and were held by Aston Villa at Stamford Bridge last time out while Ballack is currently serving a three-game suspension following his red card in last month's 1-0 victory against Liverpool.
"I am 30 now and Chelsea could be the last club I will play for," said the Germany international. "My family and I really want to feel at home here.
"I like the atmosphere here, the speed of the game and the fact it seems like there is real competition to win the Premier League every year.
"I live for football. In this environment, I know I can show my qualities.
"As a team we are getting better but we need time too. Excellent individuals have to learn how to play well as a team like any other players."
