You may laugh, but if Giroud gets injured, that's exactly what we're doing. We tried the false 9 thing before, and Gervinho has since gone, as has Arshavin - Park won't play for us, Bendtner has burnt his bridges and won't play for the club again (his words) and Chamakh has left..
So Sanogo up front is exactly how it might go
Podolski has been quite poor as lone forward so he's a no go. Only player who we can rely on if Giroud gets injured is Walcott. Sanogo and his injury history is also worrying.
