Correct. Any team having Giroud up-front is going to struggle against decent opposition. It's like playing with 10 men. Not only does he not score but his overall contribution against the likes of City, Utd, Chelsea, Liverpool etc. is next to nothing (besides missing sitters). Any one of 4 Aguero, Dzeko, Negredo and Toure have done more than Giroud in the big games.
Until we have Giroud up-front we are going to struggle against decent teams and even with a haul like 53 in 60 against the bottom like we did this season we'd still not win the league.
Any suggestions that it's going to take super-quality to usurp Giroud are laughable. Any half decent striker can match his league haul at Arsenal.
