wenger isn't right, in my view. the problem wasn't speed and sharpness. it was structure.
the entire arsenal game-plan revolves around giroud holding the ball up and flicking the ball on. welbeck cannot do it yet. it's a hard skill. giroud buys the few seconds needed for the midfield to arrive.
take giroud out of this arsenal team and it is not very strong at all. put him in and it is excellent.
once he came on today, the game changed.
