Chelsea can still improve despite opening the Premier League season with four successive victories, says head coach Maurizio Sarri.
Goals from substitute Pedro and Eden Hazard gave the Blues victory over Bournemouth at Stamford Bridge on Saturday.
The result leaves Chelsea level on points with leaders Liverpool, who have a superior goal difference, heading into the first international break of the season.
Sarri succeeded fellow Italian Antonio Conte in the summer after the Blues finished 30 points behind champions Manchester City last season.
“I’m very happy with 12 points in four matches. But I always think we can do more. We can improve,” said the former Napoli boss.
“I think now for us it’s better to think of the next match. Because the gap at the beginning was 30 points. I think it’s very difficult to cover this gap in only one season.”
