How hasn't he played to his full ability at Arsenal?
If you're suggesting he has then he's clearly not this good striker people are painting him to be.
Huge stretches of games without goals, high amount of chances with low goal return, flattering performances off the bench suggesting that he should be playing all the time. He's scores 1 goal just over every 2 games, which might seem great, but the chance conversion rating is poor and this is in an Arsenal team that played through him at times. I just don't understand the sudden swell in optimism that if Giroud came to Newcastle he'd be some super striker for us.
