Arsenal kickstarted their Barclays Premier League campaign as they blew West Ham away with four goals in the space of 10 minutes at the start of the second half to run out 5-1 winners at Emirates Stadium.
The Gunners had slumped to successive defeats against Manchester City and Chelsea to leave them facing an uphill battle to regain a place in the top four. Boss Arsene Wenger knew there was no more margin for error and despite falling behind in the rearranged Boxing Day fixture to a fine strike from Jack Collison, his side found their form, equalising through Lukas Podolski's 25-yard screamer.
Olivier Giroud scored his first goal in six games to put the hosts in front just after the restart, before German forward Podolski tore the Irons apart, charging down the left to set up Santi Cazorla, Theo Walcott and Giroud again as Arsenal romped out of sight before the hour.
