Manchester United goalkeeper coach Emilio Alvarez has defended the form of David De Gea.
De Gea has worked with Alvarez for his entire time at Old Trafford and has struggled for form with his country.
"Whoever was going to follow Iker Casillas for Spain would've found it difficult," Alvarez told Radio MARCA.
Former Atletico Madrid keeper De Gea was heavily criticised after last summer's World Cup and Alvarez suspects that the media favour players that play in Spain.
"If De Gea played for one of the Spanish clubs, I'm sure that he would've had more support in certain moments," he said.
"Those of us that know him want him to be judged for who he is as a professional and leave it to him to show what kind of person he is."
Kepa Arrizabalaga started Spain's Euro 2020 qualifier in the Faroe Islands on Friday ahead of De Gea and Alvarez wasn't surprised.
"Nothing surprises me in football. We have to respect the coach's decision," he said.
