5. Germán Pezzella
http://www.youtube.com/watch?v=k4FKQC1Hp7Y Alan Pardew has wisely strengthened his back four with the capture of Mathieu Debuchy after watching his defence concede 15 goals in their last four league and cup games. However, there is rumoured uncertainty over the future of club captain and senior centreback Fabricio Coloccini, who apparently wants a "dream" move back to his native Argentina, according to his father.* Were Coloccini to leave, that'd leave Pardew needing a new centreback, and he has been linked with a move for River Plate's Germán Pezzella, who plays at centre-half. He is only 21 - nine years younger than Coloccini - and would cost around the region of £4.5 million.** Source(s): *
