Costa has scored 7 goals in four Premier League matches.

Jose Mourinho’s Chelsea is showing a new look, completely different from the typical nature of this team a year ago.

The rain of goals pouring down on Stamford Bridge on September 13 continued to delight fans of the London team.

Striker Diego Costa continued to flourish in August, the month he was the best player in the Premier League, continuing to shoot for his new team.

With four wins, Chelsea maintains the top spot in the table.

Before the new season started, experts in England said that Chelsea was the most effective team in the 2014 summer transfer period when signing quality rookies early.

Chelsea President Roman Abramovich was smiling widely in the stands.

Before the one-on-one match took place, Swansea entered the match very well, despite playing away from home.

In the 11th minute, the Korean midfielder boldly ran the ball into the penalty area and cut the ball to the left edge for Routledge.

At the end of the first half, from Fabregas’ corner kick, the former Atletico striker scored a header from close range to equalize the gap.

At the beginning of the second half, Costa scored two more goals thanks to his ability to choose the right position.

In the 81st minute, substitute striker Remy took advantage of Oscar’s pass to score his debut goal for the new team.
