Del Bosque overlooked Mata and Herrera earlier this season and has continued to do so for this summer’s friendly against Costa Rica and Euro 2016 qualifier against Belarus.
While Mata’s absence is frustrating, not including Herrera has been met by some criticism from fans and the Spanish press.
At Manchester United this season, Herrera has grown into one of the most important players in the squad. With a personal best of eight goals this season, Herrera has shown his credentials as an excellent all-round midfielder but it wasn’t enough to earn a place in Del Bosque’s squad.

Del Bosque on Ander: "Fortunately we can follow players by TV. We keep eye on everyone who's been w underage sides. So we're watching him."

Remarkably, Herrera is still yet to make his debut for the senior Spain side despite being a key member of their 2011 European U21s Championship team.
It’s a testament to the strength of Spain’s squad that they have can leave Herrera out and still be considered one of the best teams in the world but with his form continuing on an upward curve, it is now surely only a matter of time before Herrera is finally given his opportunity.
