people are so desperate for him to succeed
I think there are two main reasons for this.
1. Last season we did in fact get a taste of what Kagawa offers. He wasn't brilliant, but he was still
good. He was also improving a lot in the last few games of the season, clearly showing us that he was going to have a bright future for us. Most people on this forum, Kagawa fan or not, had Kagawa in their first XI. Then came Moyes, and Kagawa turned into a totally different player. Many people(myself included) felt that it made more sense to blame Moyes and our football under him, rather than blame Kagawa. And many still do!
Look what happened the moment he started playing consistently and we threw Mata(an actual playmaker) into the hole instead of Rooney. Kagawa was voted POTM on this forum.
2. As brutal as it sounds: failure to successfully implement Kagawa into the team = failure to play good football. Think about it for a second: can you remember a single GOOD United performance where Kagawa was on the field, but had an average game? I'd be shocked if you can remember such a game, because there's never been a game like that. The closest is Leverkusen at home, but even then Kagawa had a fairly decent game, even though he wasn't one of our top performers.
What does this mean? It means that when the team plays well, Kagawa plays well. Usually
really well.
And I know: it's nice to have a player like Ronaldo, who has the ability to make the difference on bad days as well. But surely, there has to room for catalysts like Kagawa as well? You know, players who make others play better? Dortmund certainly found room for Kagawa, and yes, even for Dortmund Kagawa was not likely to make the difference on bad days.
To me, it seems like a loser mentality to want players who can make the difference on bad days. Why? Because a team of winners should really only have a handful of bad days per season. If having a bad day is a regular occurence, then we're doing something wrong. If we can't make a catalyst like Kagawa work out, we're doing something wrong.
