4) Mikel Arteta
Arteta provides stability and consistency in the midfield, but his poor performances during big matches, and his lack of mobility mean that if Bender or Khedira were to arrive – he might no longer be needed. Alex Oxlade Chamberlain can also play centrally, as can Jack Wilshere, Mathieu Flamini and Aaron Ramsey, and even the ever-injured About Diaby – meaning his sale could go relatively unnoticed.
