The Blues lead the Premier League by three points after five games, despite having had their winning start brought to an end by former hero Frank Lampard’s late equaliser for Manchester City at the Etihad Stadium last weekend.
While scoring 16 times in the league, though, the Stamford Bridge outfit have a worse defensive record than newly-promoted Burnley, with seven goals shipped to date.
But when asked if Chelsea need to get better defensively, Mourinho said: “It is not just defensively. It is in every aspect that we need to improve.”
The Villans beat Chelsea 1-0 at Villa Park in March, but Mourinho was quick to minimise the significance of that result, while acknowledging Paul Lambert’s team’s fine start to the campaign.
“Last season is last season. This season is this season. They are second,” Mourinho added.
“They have 10 points and that is the important thing. It is a game between the leader and the second position – they have the same points as Southampton.”
