Costa makes Premier League history at Stamford Bridge

Chelsea is enjoying life after Fernando Torres ... and they can thank Diego Costa for that.

The Spanish hitman has been in incredible form for the Blues. He was at it again on Saturday, notching a vital equalizer against Swansea just before halftime.

Costa became the second player in Premier League history to score in each of his first four games, joining Micky Quinn. He added two more goals in the second half, forming a lethal combination with Cesc Fabregas.

He's scored seven goals this season, more than 11 of the 20 teams in the league.

Chelsea have Didier Drogba in his prime again, this time in the form of Costa.

Be scared, Premiership. Be very scared.
