Herrera says De Gea's taste in music isn't for him.
“I couldn't share a room with David because he's always singing," Herrera said on a video by Unscripted. “He's always playing horrible music.
“He likes to play very, very old music from Spain. Sometimes I tell him that he looks like my granddad.
“That's why I try to be as far away as possible when he's playing music."
