Aymeric Laporte (Athletic Bilbao)
19 year-old French defender Aymeric Laporte is arguably the most exciting young defender in the game, with his performances at the back for Athletic Bilbao showcasing a maturity beyond his years.
Laporte signed a new deal at San Mames in December, and though his release clause amounts to €36 million, it could prove a sound long term investment.
Inigo Martinez (Real Sociedad)
22 year-old centre back Inigo Martinez is one of the great hopes of Spanish football, with his solid matches for Real Sociedad last season crucial in helping the team reach the UEFA Champions League this term.
Martinez has continued to deliver consistently good performances in the current campaign, and knows La Liga well.
