Mesut Ozil has sometimes divided Arsenal fans since his £44 million move to The Emirates. The German international did not set the world alight straight away, struggling for form and fitness. This season though he has been a key figure in their title challenge with three league goals and more crucially 16 assists. His form has been so good that leaked documents have come out noting that Real Madrid could buy the German back. Well, at least they have a buy-back-option on Ozil assuming that Arsenal accept a bid from any other Spanish club. Madrid would have 48 hours to match the bid. Regardless, it’s unlikely to happen but some Arsenal fans may be worried.
