3. Alex Song
Could Arsene Wenger sensationally re-sign one-time Emirates favourite Alex Song from Barcelona? In April, the
Express reported that the French manager was pondering re-signing the Cameroonian star, 12 months after he quit North London for Barcelona. His time there has been marred with difficulty however as he was named alongside Real Madrid playmaker Luka Modric as one of the two worst signings of 2012 in a poll carried out by Spanish newspaper
Marca. The 25-year-old was also limited to just the 20 La Liga appearances last season and didn't register a single goal or assist for his new club in his debut season. Arsenal could be set to revive Song's flagging career this summer by making a surprise bid and it is unlikely that Barcelona will stand in their way, considering he is way down in their pecking order.
