#8 Ander Herrera
After a slow start to life in Manchester under Louis van Gaal, Herrera seems to have finally found a home in a defensive midfield role under Jose Mourinho.
The Spaniard came through the ranks of Real Zaragoza’s academy, helping the team return and cement their place in La Liga, playing alongside the likes of now Atleti captain, Gabi, in the middle of the park. In 2015, his time with the club came under scrutiny after it was revealed that Zaragoza may have fixed their 2-1 win over Levante in 2011; this was the game that had guaranteed their continued stay in the Spanish top-flight.
The Levante players were allegedly paid an eye-watering sum of €965,000 to lose the match, and Gabi had €85,000 deposited in his bank account for similar purposes. If found to have colluded in the deal, Herrera could face up to 4 years in prison and a fine of more than 5 million euros.
