Chelsea striker Didier Drogba has expressed his belief that Diego Costa has made a better start to life in the Premier League than when he joined the club back in 2004.

The Spain international has netted four goals for Jose Mourinho's side in his first three games in the top flight, including a brace in the Blues' 6-3 win over Everton on Saturday.

Drogba scored 10 goals in his first season in the Premier League, and he has admitted that the signing of Costa is proving to be a hit already.

"Diego Costa has started very well," Drogba told reporters. "He looks special. He's scoring goals and helping the team. He's settled right in - and he's started much better than I did!"

Chelsea are top of the Premier League after recording victories in all of their three games so far this season.
