Arsenal manager Arsene Wenger has become famous for his eye for talent, often buying young players and selling them on for double or triple what he got them for. Though they haven’t always worked out as well as he would have liked.
5. Andre Santos
Andre Santos, just say the name and Arsenal fans shudder as a look of disappointment appears of their face. The Brazilian wing-back was famed for his pace and passing ability at Fenerbahce, it was thought by many that he would fit into the Wenger system seamlessly, but how wrong could we all have been? Often looking lazy and uninterested, his life of the pitch was also criticized, as the former Corinthians defender had been fined for speeding among other offences. Now at Flamengo, he seems to have turned himself around as he helped his new club to the Brazilian cup title.
