Herrera: I'm in the Spain squad because of Mourinho
Joining Manchester United from Athletic Club in 2014 was a huge move for Ander Herrera, who has thanked Jose Mourinho for his recent senior international call-ups.
The Portuguese coach has made Herrera an important part of the United set up so far this season, who is now playing regularly as one of two defensive midfielders above the back four.
"I am in the national side thanks to the opportunity Mourinho has given to me to play in a role that I feel comfortable," said Herrera to Daily Mail.
"The team is enjoying every day with him. The workouts are dynamic, we always play with the ball so that we never lose concentration.
"He will speak his mind and tell you what he thinks about you, things you will like, and things you will not."
Tuesday's game at Wembley Stadium may see Herrera make his debut for La Roja, as they face England in a friendly.
