Khedira isn't a pure CDM. He's more of a false 6, he bombs forward a lot for a CDM and he's not the most amazing passer. I feel that you need either a pure destroyer who then lays it off to the opposition or you need a better version of Arteta, an Alonso who relies on interceptions and has very good passing ability. Will say it again, Ruben Pardo would fit Arsenal, but they won't sell him for cheap. €32M release clause for a 21 year old who's only had his breakthrough season last season.
