#8. Walter Samuel
Real Madrid were interested in Samuel as they sought a strong leader for their defense in 2004. However, he failed to make any impact and was not able to find his feet which promptly led him to return to Italy the following year where his defensive performances soon picked up. PREVIEW FOR #7: The Frenchman enjoyed his time at Arsenal under Arsene Wenger and certainly boosted his value. After his arrival he soon got on bad terms with the team, the fans and his manager and ultimately led to him being banned from a few games because he refused to train. He soon went back to PSG.
