Alvaro Morata was unhappy to be omitted from the latest Spain squad, according to Chelsea team-mate Marcos Alonso.
Blues striker Morata scored his first goal of 2018 in the FA Cup quarter-final win over Leicester City on Sunday, ending a run of 13 games in all competitions without scoring.
The 25-year-old's dip in form, combined with a back injury, saw Antonio Conte experiment with Eden Hazard as a false nine and use January arrival Olivier Giroud in place of Chelsea's record signing.
Alonso admits it has been a tough time for his compatriot but he is confident the former Real Madrid man, who was overlooked by Julen Lopetegui for this month's friendly matches, will enjoy a strong end to the season.
