5. Javier Pastore | Paris Saint-Germain

Javier Pastore hasn't lived up to expectations at Paris Saint-Germain since completing his €42m move from Palermo in August 2011.

The 24-year-old has been in and out of the Argentina squad over recent years and needs to be playing regular first-team football somewhere in order for Alejandro Sabella to consider him for next summer's tournament.
