Diego Costa strikes again in Chelsea romp against West Brom
Brazilian bags his 11th goal of the season as Chelsea go 12 unbeaten

Diego Costa scored again as Chelsea established a seven-point lead at the Premier League summit on Saturday by comfortably beating 10-man West Bromwich Albion 2-0 at Stamford Bridge.
Costa opened the scoring in the 11th minute, leaping into the air to control Oscar's left-wing cross on his chest and then slamming a side-foot volley past Ben Foster for his 11th goal of the campaign.
Eden Hazard added a second in the 25th minute, smuggling a deflected shot beneath Foster from Cesc Fabregas' corner, before West Brom's Claudio Yacob was sent off for a two-footed challenge on Costa.
It was comfortable but I thought in the first half we played amazingly well
The victory saw Chelsea set a new club record of 12 unbeaten games from the start of the season.
Jose Mourinho's side are now seven points clear of second-place Southampton, who visit Aston Villa tomorrow, and remain eight points above defending champions Manchester City, who won 2-1 at home to Swansea City.
"It was comfortable but I thought in the first half we played amazingly well," said the Portuguese. "In the first half we have to be 3-0, 4-0, 5-0 up. But the quality of our football was there. I don't remember seeing many times football of that dimension."
