The most likely of the army of supposed Arsenal transfer targets to actually move to North London is Turkish central-midfielder Nuri Sahin. The 23 year old signed for Real Madrid last summer after being the orchestrator for Borussia Dortmund in their league-winning campaign. Back then he was seen as an incredibly promising talent, Madrid forked out 12 million Euros for his signature and gave him Zinedine Zidanes hallowed number 5 shirt. He plays a deep lying midfield role, similar to Arsenals own Alex Song or Mikkel Arteta, which means that he would provide excellent depth in that position (especially seeing as Song is being linked with Barca). Sahin is also equally capable of playing a slightly more advanced role, thus providing cover for the injury-stricken duo of Wilshere and Rosicky. His recent deployment as a left-back by Jose Mourinho in pre-season is fantastic because it would mean that he could cover that position too, making Sahin a true utility player that would greatly benefit a team like the Gunners, infamous for their injury list. These qualities make Sahin a contender to be the missing puzzle piece in Arsenals hunt for trophies; and in my opinion hes definitely worth a chance as he wouldnt cost the club a penny in transfer fees.
