Diego Costa's second-half goal earned Chelsea a 2-1 win over Liverpool on Saturday as the unbeaten leader negotiated another tough test in its relentless challenge for the Premier League title, according to AP. Dropped by Spain on Friday to allow him to recover from a string of nagging injuries, Costa started at Anfield and drove home his 10th league goal of the season in the 67th minute after Cesar Azpilicueta's cross was parried out. Chelsea had to come from behind to secure a ninth victory in 11 games after German midfielder Emre Can scored for Liverpool from a deflected shot in the ninth minute. Gary Cahill equalized with a scrappy goal from a corner in the 14th. Chelsea started the weekend four points clear of second-place Southampton. -- SPA 18:10 LOCAL TIME 15:10 GMT تغريد
