I could see him going to West Ham.
Wenger has a history of selling strikers to West Ham.
Wright, Suker, Hartson even Ljundberg has played as a striker occasionally.
So Giroud would be guaranteed first team football at a club at his level, and we could actually go out and buy a world class striker.
Saying that, if Wenger stays so will Giroud, and he will be our starting striker next season after Sanchez is sold and Welbeck gets another long term injury.
