5. Santi Cazorla
Santi Cazorla has enjoyed a terrific first season at the Emirates since his move from Malaga this summer, scoring 7 times and providing 5 assists in 24 appearances so far for Arsenal. Though the prospect of Cazorla leaving the Gunners so soon into his contract might seem unlikely, Roman Abramovic might be tempted to at least test the waters with an offer. He has been seeking Spanish-born players in a bid to help kick-start Fernando Torres' career for the Blues, and the likes of Mata and Cazorla rampaging through midfield would do just the trick. It's not like Arsenal aren't accustomed to losing their best players to Chelsea either - Ashley Cole?
