A big weekend of football saw Chelsea climb to the top of the Premier League table with a narrow victory over Middlesbrough.
Manchester City's title challenge also gained strength with a win against top-flight strugglers Crystal Palace but United dropped points against Arsenal.

1. Antonio Conte appears to be the first manager to find a way to control Diego Costa's wild side without losing the competitive edge from the Chelsea striker's game.
Spanish star Costa became the first Premier League striker to get into double figures with the winner at Middlesbrough but also showed an unselfish side by creating four chances for team-mates.
