Marcos Rojo:
The Sporting Lisbon defender is immensely versatile and can play as a centre back or as a left back, like he does for Argentina. The 24 year old is one of the best young talents in Europe and has attracted the likes of Liverpool and Tottenham Hotspur over the past few months. His running abilities with an immense work rate will give Arsenal that extra zip in attack and provide a different dimension in their attacking outlet from the wings. The Gunners can weigh up offers for the Argentine in the summer and with Rojo been an integral part of his club side in Portugal, it could be a massive coup for the London side if they acquire his signature.
Although he cannot be truly believed in the first choice role, be it at left back or centre back, but if Wenger believes that he can get the best out of the Argentine by effectively rotating him then Rojo is the man for Arsenal. His performances in the ongoing World Cup for Argentina have been solid if not spectacular, which should make a case for Arsene Wenger.
