Defender Marcos Alonso has revealed that Chelsea teammate Alvaro Morata was disappointed with not being given a place in the latest Spain squad.
Morata has scored just once for Chelsea since the start of 2018, with that goal coming during the Blues' 2-1 victory over Leicester City in the FA Cup on Sunday.
However, it was not enough for Morata to be selected in the group to face Germany and Argentina, and Alonso has said that his compatriot was "not happy" with being left in West London.
At a press conference, the 27-year-old told reporters: "Alvaro wasn't happy. He's gone through a couple of difficult months because of a back problem. He's at 100%, he got back to scoring the other day.
"I hope he helps us at the end of the season. He's really important and I hope he's at the World Cup."
Spain boss Julen Lopetegui has said that Morata is still in contention to feature at this summer's finals in Russia.
