Middlesbrough - Chelsea live updates

FULL TIME: Middlesbrough 0 Chelsea 1 (Costa 41)

Time almost up here and Chelsea are headed for the top of the table.

Gibson goes down after a challenge on Costa but looks okay. Hazard off to be replaced by Oscar.

Movement on the Chelsea bench...

There will be FOUR additional minutes.

Chelsea sub: Ivanovic on for Moses.

Boro sub

Can Boro muster one last clear cut chance? Only one shot on target in the match so far.

Dangerous cross from Downing but it’s fractionally behind the onrushing Fischer.

Luiz lines it up for his dipping specialty but it dips over the bar, not under it.

Chelsea win a free kick right on the edge of the box after Ramirez fouls Hazard. Another decent chance.

Not yet!

Chelsea break through Hazard but Boro do well to regroup before clearing.

Into the final ten minutes and time not on Boro’s side. Traore does well to get in a cross but Chelsea clear.

Chelsea sub: Pedro off for Chalobah

SAVE! Courtois gets down well to save Negredo’s opportunistic volley. Good effort.

The Blues have kept five consecutive Premier League clean sheets for the first time since a six-match streak in 2010.

Fischer and Negredo left frustrated as Traore slashes over the bar.

Now Chambers booked for tugging back Diego Costa.
