I think arsenal wil miss diaby in dis derby cause in that sunderland game i actually missed him. Diaby has the height and also the sleek runs that unsettles defence. He also assists song in given fabregas that needed cover in midfield, dis allows fab to move deeper into attack zone. Dat is de main reason 4 the 433 formation. I dont think denilsön can cover up. But we shal stil keep de faith. Just hope e silva utilizes his chance
