Mourinho says manchester united are champions of wrong refereeing decisions

I think there may be a slight mistake there!

José Mourinho, the former Manchester United manager, is known for his outspoken nature and sometimes controversial comments. However, I'm not aware of him ever saying that Manchester United are the "champions of wrong refereeing decisions".

It's possible that you may be thinking of a different quote or statement made by Mourinho, or perhaps a joke or a play on words. If you could provide more context or clarify what you're referring to, I'd be happy to try and help you out!
