“It’s a different profession on the pitch, objectively it’s hard to understand," the 40-year-old said. "But I know that football is so popular that everyone feels the need to comment.
“As players we accept it, if there’s a journalist who criticises us then we may or may not take it badly, but we accept it. We don’t feel protected though, we’re vulnerable to those who don’t understand what we do and influence public opinion.
“Nobody really seems to understand, for example, that the most difficult things for a goalkeeper can be the things that other people don’t see: speaking at the right time, making a suggestion to a defender," he explained.
