Sanchez fires Arsenal up to second: West Ham have no answer as Chilean hits 14-minute hat-trick in five-goal rout

WEST HAM 1-5 ARSENAL - For the briefest of moments in the second-half, West Ham stirred. They were a goal down but they were going at Arsenal, Dmitiri Payet was in the game for the first time and the home crowd were out of their seats, urging them on. At Upton Park, this would have been a test of bottle for any visiting team. Here in this spacious Olympic home, Arsene Wenger simply reorganised a little, made a change and watched his team score four in 12 minutes as Arsenal ran riot.
