Arsenal manager Arsene Wenger has admitted that his side must stop Diego Costa if they are to have any chance of taking something from leaders Chelsea on Sunday, BBC
The two sides go into the game unbeaten in the Premier League this season, but the Gunners are six points behind their hosts as they have drawn four of their opening six matches. Wenger has never beaten Mourinho as a manager in 11 previous attempts, and he returns to the scene of the 6-0 embarrassment against Chelsea last season.
Costa was brought in by Chelsea from Atletico Madrid over the summer to address a lack of goals scored by their strikers, and he has made an instant impact despite not being fully-fit and training regularly. So far, he has scored eight goals in six Premier League outings, including a hat-trick at home to Swansea City.
And Wenger believes that Costa’s presence represents a significant danger for his side on Sunday. He said: “Costa has the aspects that you like. He is focused, always determined and ready for a fight.
“He has done fantastically well and he is a very efficient player. The timing of his runs and his determination, his killing determination – you feel he is a killer, he has that in him when in front of goal.”
