LONDON, April 8 (Reuters)- Substitute Javier Hernandez stole an equaliser to earn West Ham United an unlikely point in a 1-1 draw with Chelsea at Stamford Bridge on Sunday.
Chelsea had dominated the London derby for 73 minutes, leading for almost half that time after Cesar Azpilicueta poked home in following a short corner.
Their Spanish striker Alvaro Morata also had the ball in the net twice but was narrowly offside each time.
West Ham, who had been much improved in beating Southampton 3-0 a week ago, offered little until Hernandez’s intervention soon after coming on.
There was an emotional tribute before the game, and after eight minutes of play, to Ray Wilkins, the former Chelsea captain and assistant manager, who died in midweek. (Reporting by Steve Tongue Editing by Ian Chadband)
