Costa secures Chelsea’s ninth straight league win

Chelsea moved back to the top of the Premier League on Sunday and made it nine successive league wins as Diego Costa scored the winner against West Brom.
The Spain striker punished a hesitant Gareth McAuley in the 76th minute to rob the defender of possession and curl a brilliant left-foot shot past Ben Foster.
West Brom had looked like earning a point after restricting the Blues to just one other shot on target, a 30-yard David Luiz free-kick.
Chelsea also came close through an N’Golo Kante shot that deflected off Pedro and rolled just wide of the post.
The Baggies had early chances through a Chris Brunt shot that fizzed wide and Salomon Rondon shooting across goal.
Chelsea have now moved three points ahead of Arsenal while West Brom stay ninth.
