Chelsea made light of striker Diego Costa's absence to extend its lead at the top of the Premier League to seven points on Saturday with a 3-0 win at champion Leicester City.

After a Harry Kane-inspired Tottenham Hotspur and a ruthless Arsenal side kept up the pressure at the top with 4-0 victories, Chelsea found an unlikely hero in wing back Marcos Alonso, who scored the team's first two goals at the King Power Stadium.

All the pre-match ballyhoo had been about Costa, the league's leading marksman, having been dropped from Antonio Conte's squad amid reports of a fall-out over his fitness.
