Isco unloads his frustrations with Zidane

MADRID - Hat-trick hero Isco said it was a relief to play for Spain as he feels Real Madrid coach Zinedine Zidane has no faith in him.

Spain destroyed Argentina, which was without Lionel Messi, 6-1 in a friendly on Tuesday as Isco stole the show with his triple at Wanda Metropolitano Stadium.

The 25-year-old has become a key player under coach Julen Lopetegui and is expected to start at this summer's World Cup in a front three alongside Diego Costa and David Silva.
