Giroud silences critics

Olivier Giroud helped Arsenal silence their critics as the France striker's double inspired a much-needed 5-1 victory over West Ham on Wednesday.
Arsene Wenger's side had been subjected to scathing criticism from fans and pundits after successive defeats against Manchester City and Chelsea seriously damaged their bid to finish in the Premier League's top four.
Wenger was reported to have held crisis talks with his players this week and the Gunners looked set to hit a new low when Jack Collison gave West Ham a shock first-half lead at the Emirates Stadium.
But Arsenal bounced back in emphatic fashion, equalising through Lukas Podolski and then taking the points after Giroud sparked an astonishing spree of four goals in 10 second-half minutes, with Santi Cazorla and Theo Walcott on the scoresheet before Giroud completed the rout.
Arsenal remain in sixth place but their first league win in four matches moves them within four points of fourth-placed Tottenham in the race to qualify for the Champions League.
Arsenal had been warned but, given their defensive frailties this season, it was no surprise they didn't learn the lesson as West Ham took the lead in the 18th minute.
Giroud, attempting to head clear a corner, could only reach the edge of the penalty area, where Collison, left completely unmarked, had time and space to control and lash a fierce strike past Wojciech Szczesny.
Often accused of lacking the character to deal with that kind of momentum-changing moment, Wenger's players for once showed impressive spirit and hit straight back to equalise within four minutes.
Cazorla and Jack Wilshere were the architects, working the ball across midfield to Germany forward Podolski, who advanced unchecked before drilling a long-range strike past Jussi Jaaskelainen for his 11th goal of the season.
