Real Madrid coach Carlo Ancelotti says Barcelona counterpart Ronald Koeman deserves better from fans after Sunday's carpark incident.

Koeman's car was mobbed by unhappy fans after defeat at home to Real Madrid on Sunday.

“It was an annoying feeling, I feel for Koeman, who shouldn't have to suffer things like that, it can't be tolerated," said Ancelotti.

The Italian said “it's a social problem, not just a football one".

“It's a lack of respect for the person, not the coach. It shows society has a problem. Koeman is a person, who works as a coach."
