#3 Jordi Alba - £63 million
Jordi Alba has blossomed himself into one of the best left-backs in the world, if not the best, during his spell at Barcelona. The Spaniard has developed a healthy relationship with the Argentine megastar - Lionel Messi, which has helped Barcelona find success in the past few years.
Alba is mostly known for his lightning speed that allows him to burst forward with menace against oppositions, kick-starting forays as a result. His brilliant performance versus Real Madrid is a testament to this feature.
Throughout the all-important match, the former Valencia ace kept tormenting Real Madrid's back-line with his baleful runs, catching the defenders off guard on a number of occasions. He also assisted Barca's opening goal in the 11th minute. Undoubtedly, Alba has improved in leaps and bounds under the tutelage of Ernesto Valverde and owes a lot to the Spanish manager.
