#1 Marcos Rojo
Marcos Rojo signed for Manchester United from Sporting CP in 2014 at a transfer fee of £16 million. The Argentine started as a left back for United but moved to a center-back position later.
Rojo is someone who has always given his hundred percent and never refrained from lunging into tackles. He is an old school no-nonsense defender who formed a significant partnership with Phil Jones under Jose Mourinho.
However, injuries took the better of him as Marcos struggled to get a run of games under his belt. His last appearance was against Valencia in the Champions League, but since then, he has been out of the squad due to a mysterious injury. United are supposedly preparing a massive bid for a defender in the summer and would need to sell a couple of players of their own to fund that transfer with Rojo being the one who could face the ax.
