Things haven't quite gone to plan for Manchester United this season, with new manager David Moyes enduring a difficult season since replacing Sir Alex Ferguson. The Red Devils are fighting for a Europa League place rather than the Premier League title, which is a sign of how far they have fallen in just one season.
Moyes is now expected to conduct a full scale overhaul of his squad this summer as they look to get back to the pinnacle of English football. The squad is littered with ageing players well past their sell by date and a number of players who just aren't good enough.
A key area for Moyes to strengthen this summer is in central midfield, where £27.5m summer signing Marouane Fellaini has failed to impress. In a recent scouting mission to Portugal, Moyes watched Benfica vs Porto and was reportedly interested in Benfica's Argentine midfielder Enzo Perez - but just who is the 28-year-old? Here are five facts on the midfielder...
- Perez began his career with Argentine side Godoy Cruz, becoming the goalscorer of the club's first ever goal in the top flight in 2006.
- His impressive displays there resulted in a 2007 move to Estudiantes, becoming a key player as they went on to win the Copa Libertadores in 2009.
- His key role in the Estudiantes side earned him his big move to Europe in 2011, joining up with Benfica for €5.5m on a five year contract.
- Perez initially struggled to make an impact in Europe, and was sent back to Estudiantes on loan in order to get playing time following an injury.
- Perez's success with Benfica now is down a positional change - originally a right-sided midfielder, Perez has converted to central midfield after the departrues of Javi Garcia and Axel Witsel in 2012, forming a strong partnership with now-Chelsea star Nemanja Matic in Portugal.
