You were saying you didn't understand why so many United fans were so critical of him and I explained that. I'm not playing the De Gea victim card, I'm pointing out that there was a period when literally everything De Gea did was scrutinised to the nth degree, with many goals that weren't actually his fault being blamed on him, whilst Hart was getting away scot-free with any errors and was being hailed as one of the best keepers in the world. That rankled with a lot of United fans, and that coupled with Hart being extremely arrogant has meant that his current run of frequent errors is particularly pleasing to some because he's making himself look like a right muppet. I'm not sure why you think it's so absurd that United fans are taking pleasure in their biggest rival's first choice keeper being a bit shit at the moment because I assure you that they'd be laughing their arses off if the same was happening to De Gea.
You came into this thread asking why people didn't like Hart and said he's not been as bad as people think. There have been multiple explanations for why people don't like Hart, and without any real elaboration on the "as bad as people think" part people can only assume that you're referring to the general consensus in this thread. A consensus which acknowledges he was the league's best keeper when City won the title, but also points out he was a bit dodgy last season and has been particularly terrible this season, especially considering he's supposed to be the first choice for a title chasing side. Your defence of him is quite frankly very strange, because at the end of the day, who gives a flying feck if United fans are taking pleasure in and over-exaggerating the misfortunes of their biggest rivals goalkeeper?
