Just read somewhere that Pires reckons he's what Arsenal need in midfield. Can someone who's been watching him regularly for Madrid tell me what exactly does he add to the team? I've hardly ever seen Khedira play and I'd like to know what his strengths and weaknesses are.
I never understood why there are people who say that Arsenal would need Khedira. They probably never saw him play.
He is at his best when he has a player next to him who does the creative work and sits back as the deepest midfielder in front of the defense.
Like Xabi Alsonso at Real and Schweinsteiger at Germany. A midfield I could see him work in would also be Juventus if they'd sold Vidal and got Khedira to replace him next to Pirlo.
Someone sitting deep allows him to use his energy to run around a lot in midfield, basically playing box to box or sometimes even making runs on the wing if space opens up there. To play a pure DM who should protect the back 4, he lacks the discipline and possibly positional awareness.
A good example could be seen about 2 or 3 seasons ago in the German national team when Schweinsteiger was injured and Löw had to play Kroos and Khedira in midfield.
Kroos was not yet comfortable playing a CM role let alone as the deepest player in midfield.
So it was on Khedira to sit deep and play as a DM. He couldn't do it and was criticised as a headless chicken because he always made runs -like he always does- and abandoned his position, leaving the backline exposed.
So, if you want a replacement for Arteta and Flamini, Khedira is not your guy. His natural position is the same as Ramsey's in the Arsenal squad.
