Costa scores a brace as Chelsea scores 6 goals in a 9 goal thriller with Everton

Diego Costa scored twice as Chelsea clinched a thrilling victory over Everton to keep up their 100% start to the new Premier League season. The Toffees fought back from conceding two goals in the first three minutes and had hope of a remarkable comeback as the sides traded five goals in a manic 10-minute second-half spell. But ultimately Jose Mourinho's side survived an incredible match to take the three points with a performance that showed their progress since a 1-0 defeat at Goodison Park this time last season.
