LONDON (Reuters) - Chelsea made light of striker Diego Costa's absence to extend their lead at the top of the Premier League to seven points on Saturday with a 3-0 win at champions 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 their first two goals at the King Power Stadium.
