Chelsea took the spoils in a bad-tempered game against Arsenal, marred further by two red cards for the visitors.
Arsenal started so brightly, Alexis Sanchez and Theo Walcott combining well from the off, looking lively but lacking a cutting edge.
Diego Costa failed to make any goalscoring impact in the first half, but he did manage to manipulate the game by getting Gabriel sent off in added time. Costa had clashed with Laurent Koscielny in the box, lashing out more than once, and Gabriel appointed himself his team-mate’s protector. After he and Costa had both picked up bookings, he was then lured into a sly kick at the Chelsea man, which sealed his fate.
Kurt Zouma scored the first goal of the game eight minutes into the second half, hurling himself at a free kick to take the ball past Cech.
Laurent Koscielny joined his colleague in the changing rooms with ten minutes to go, picking up a red card for a foul on Cesc Fabregas.
And substitute Calum Chambers rounded off an afternoon of ignominy when he deflected Eden Hazard’s shot into his own net as the clock ticked over to 90 minutes.
