Criticism affects everyone. They're footballers but they're people with feelings as well. And it isn't just English/British players who are affected by criticism (which is a stupid claim), so I'm not sure why you're trying to make out that it is.
Mario Gomez: ‘The recognition and appreciation is higher abroad than back home. They think I’m a very good player. I felt a lot of pressure before our first game against Portugal because of the criticism in Germany. I felt under observation and didn’t play as freely as I wanted.'
Sergio Ramos: "We respect the critics, but it hurts that a section of the fans criticise you after all that we've done."
It's natural, and probably more hurtful for Cleverley as he was here from a child and loved the club. He's not using it as an excuse for not playing well either, but his performances last season were no better or worse than some of our other players who get far less criticism because they aren't used as the scapegoat by large sections of our fans.
