Wenger lauds Giroud for sparking Gunners

French striker's return to form boosts Arsenal's top-four hopes

Arsene Wenger believes Olivier Giroud's decisive contribution to Arsenal's vital 3-1 win over West Ham is a sign the France striker is back to his best in time to fire his side into the Champions League.

Wenger's team climbed back above Everton into fourth place in the Premier League thanks to Giroud's inspired strike and a brace from Lukas Podolski at Emirates Stadium on Tuesday.
