Spain coach Vicente del Bosque named his squad on Tuesday, for the upcoming friendly against Costa Rica on June 11th, which is followed by an important EURO 2016 qualifier in Belarus on 14th June.
Despite their best efforts and strong form with Manchester United this season, once more, the Spain coach has neglected to call up either Ander Herrera or Juan Mata, amongst his midfield options for the two games.
For 27-year-old Juan Mata, there hasn't been a Spain appearance since the disastrous 2014 World Cup campaign in Brazil, which came in the 3-0 group victory against Australia and was accompanied with a goal.
This latest omission will take the Manchester United favourite beyond a year, since his last appearance for his country, having achieved 34 caps and scored 10 goals for La Roja.
As for Ander Herrera, the situation is somewhat different, but nonetheless surprising, for a player who according to Whoscored.com statistics, has been United's third most highly rated player of the 2014-15 campaign in the Premier League.
However, 25-year-old Ander Herrera has only made three senior appearances for Spain thus far, which all came during the 2012 Olympic Games in London. Since then and perhaps inexplicably, Vicente del Bosque hasn't considered the talented midfielder, as part of his considerations.
Even amidst a supposed overhaul of his squad, featuring the gradual introduction of new players, or opportunities for those who were previously on the fringes of his plans, the Spain coach continues to turn a blind eye to the Manchester United pair.
When looking at the current crop of Spanish stars featuring in the Premier League, this latest squad call has also leaned more heavily towards La Liga, with just four players from the English top-flight included.
Manchester United goalkeeper David De Gea does make the squad, whilst there's also space for David Silva of Manchester City, Santi Cazorla of Arsenal, along with Cesc Fabregas of Chelsea. All certainly merit their calls.
Whilst on the one hand, Mata and Herrera having the opportunity to rest fully this summer, can be viewed as a positive for Manchester United, both players must certainly be wondering what more they need to do, to convince Del Bosque they're worthy of his attention.
