Costa hands Jose the last laugh again: Striker's see Gabriel sent off while he somehow escapes red card... leaving Zouma and Hazard to seal Chelsea win over NINE-man Arsenal

CHELSEA 2-0 ARSENAL - ROB DRAPER AT STAMFORD BRIDGE: The last laugh always seems to go to Jose Mourinho, especially when it involves Arsene Wenger, still unable to beat his adversary in the Premier League. A match which pivoted on Diego Costa's gamesmanship saw Arsenal reduced to nine men and fighting a losing battle which may yet revive Chelsea's season. It was all more galling given that they had started well and appear to have overcome their fear of Chelsea of late. Yet they were drawn into the kind of fight they could never win, a streetwise scrap of flailing arms and snide flicked kicks. On such details this game was won and lost.
