Why do Arsenal keep hitting longer balls either from the back or crossfield to midgets on the wing who lose every single header. Balls into the box for Giroud is one thing, a long ball over to Sanchez or campbell is a constantly failing plan.
Yes Sanchez can be good in the air and scored some nice goals but 9/10 of those are static defender and Sanchez on the end of a run, not two players with plenty of time to get to the end of a long ball.
Arsenal have had two 5-10 min spells looking okay but have looked awful the rest of the game.
