4. Del Bosque and Casillas at war

It’s believed there were a few arguments between the manager and the veteran goalkeeper, Iker Casillas, before and during Euro 2016.

Del Bosque dropped Casillas, 35, to the bench for the first time since the goalkeeper made his debut at a major tournament at Euro 2000.

David De Gea, 25, took Casillas' place after pulling off incredible saves for Manchester United in the past few seasons.

Casillas, who captained Spain to Euro 2008, World Cup 2010 and Euro 2012 glory, was not happy with the manager's decision as he felt ready to lead his squad out once again. Should Del Bosque have gone with experience ahead of young blood?
