CB: Javi Martinez(Spain | FC Bayern Munich)
A starter at one of the best clubs in Europe, Javi Martinez was not able to nail a place down in the Spanish team with the midfield jam-packed and the two centre-half berths cemented by Serio Ramos and Gerard Pique, with Cesar Azpilicueta ably deputising for any of the back four. In the squad for all 3 of Spain's major tournaments, Martinez was ruled out of the Euro 2016 due to injury. Injuries have dampened the Bavarian defender/midfielder in the past two seasons, a factor that will have played a part in him not being considered for Spain.
He had made 37 appearances for Bayern in all competitions, starting many. However, he will need more to do if he were to get into this Spain squad.
