We have a lot of former players in the media so there is a lot to dislike, the more you see people the more you have to dislike.
Giggs is probably number 1, but I don't like Rooney as a person, Neville is very disingenuous and political, Ole can't take accountability, throws people under the bus and comes off like a weasel. I'm sure Ole isn't a bad dude as no one has anything bad to say about his character, it's just how he comes across to me. But then again, you have to question someone's authenticity when no one has anything bad to say about you.
To switch things to make them more positive. I really like Valencia, Keane, Vidic, Schweinsteiger, and Nani seems like a fun dude. I like Ronaldo, he did not shit on the legacy of the club like some of the cool-aid drinkers have suggested, he just held the club to a standard and highlighted the club couldn't stand up to any sort of elite level like we claim it does. Some people coddle things they love to protect them and their image of them, and others criticise them because they want to make them better.
If we're going to add a cringe category then it's Rio, Foster and Evra.
