Costa sparkles as Chelsea down Saints

Diego Costa's sublime strike sealed Chelsea's 2-0 success against Southampton on Sunday as the Blues chalked up a fourth successive Premier League victory.

Costa doubled Chelsea's lead with a fine finish from 25 yards after Eden Hazard had put Antonio Conte's side ahead early in the first half at St Mary's. Inflicting Southampton's first home league defeat since February gave Chelsea four league wins in a row for the first time since April 2015, when they were on the verge of lifting the title under Jose Mourinho.
