Middlesbrough 0-1 Chelsea: Watch highlights as Diego Costa scores winner

Watch highlights as Diego Costa's 10th goal of the season sent Chelsea to the top of the Premier League table with a 1-0 victory over Middlesbrough.

Costa's 41st-minute strike was all the Blues had to show for their efforts at the Riverside Stadium with Boro keeper Victor Valdes in particularly stubborn form, but it was enough to secure a sixth successive league win and clean sheet.

Chelsea have now not conceded in the competition in 590 minutes and lead Liverpool and Manchester City by a point while Boro, despite their recent heroics at Arsenal and Manchester City, have now won only once in 10 league outings.

The closest Boro came to scoring was when Alvaro Negredo saw a shot saved by Thibaut Courtois in the second half.

Pedro, meanwhile, hit the bar for the visitors and also saw an effort well saved by Valdes.
