Manchester City returned to the top of the Premier League as Riyad Mahrez's early goal gave them victory over Tottenham in a scrappy encounter on a Wembley surface scarred by Sunday's NFL game.

Former Leicester City forward Mahrez, who swept home Raheem Sterling's sixth-minute cross, dedicated his goal to Foxes owner Vichai Srivaddhanaprabha, who was killed in a helicopter crash at the King Power Stadium after Saturday's game with West Ham.
