With Kagawa I don't think there's any middle-ground. He'll either become one our best and most influential players, or he'll leave us and become a massive success somewhere else(back in Dortmund, for instance). The whole situation speaks volumes about the impact of playstyle and management. Kagawa is not a sure starter for us, and he barely gets any minutes in his best position. Yet if he went back to Dortmund, a team currently superior to us, he'd jump straight into the starting lineup in his preferred position. He'd be a hero in a league that's currently easily on par with the Premier League. He'd actually have a good chance at winning the Champions League. He'd be playing for a team where the fans and manager loves him. On opposing clubs' forums, people in the transfer thread would scream for Kagawa's signing. This webiste and others would be filled with the latest Kagawa gifs.
All of this is in an alternate universe, though. We have to deal with the reality: Kagawa is a United player. So what should we do with a player of his caliber? Should we try to integrate him fully into the team, or should we waste both his and our time? Keeping him as a backup is a bad deal for both parties, so that's just postponing the inevitable transfer.
I can't be the only one thinking that something is wrong when we can't make a player like Kagawa a part of our starting XI, when we've been screaming for a player like him for years. The only reason people are so willing to not put their trust into him, is because they didn't really see him play for Dortmund. For these people, the signing didn't feel like a big one. But it was. Don't let the price tag fool you.
I sometimes wonder what it would look like in here if we signed a more famous player, like Özil or Mata, but failed to integrate him into our starting XI. My guess is that people would behave a lot more like I've behaved in this thread. When you know that a player is brilliant/world class, you obviously want the manager of your team to make it work out. Failing to do so, is frustrating. Because it leaves you with the feeling: "if not this player, then WHO?!"
That's essentially what I feel about Kagawa playing for us. If not him, then who? And when? When Rooney retires/leaves us and the AM spot is "open"?
