So Kagawa played a whole 30 minutes in the no.10 position and didn't impress. Gaspety-gasp-gasp!
I see some people jumping the gun and using this game as an argument for Kagawa not having a future as a no.10 in PL. To those people I have to ask the following: did you not watch us play last season, with pretty much the exact same players? In the last third of last season, Kagawa played roughly 70 minutes as a no.10, against 3 different PL sides. During those minutes, he was amongst the best(if not the best) players on the field, scoring 2 goals, making 2 assists, and creating a bunch of chances and nice play. If you made a youtube compilation of out only those minutes and asked a random person who knows nothing about Kagawa to compare that video to the average Rooney performance, then he'd laugh in your face and say that he'd pick Kagawa for the no.10 position any day of the week.
Now, 70 minutes against 3 PL opponents are not a lot of games to base your opinion on, and you'd be foolish to think that this alone is evidence that Kagawa is a master in the no.10 position. My point is just that today's performance against Tottenham was the exception. Not the norm. Kagawa has(since the Norwich game) played brilliantly in the no.10 position in the PL up until today. It is therefore pointless to single this performance out as the "standard".
As I mentioned earlier, I think today's performance is one of Kagawa's worst. Maybe even the worst. But was he any worse than Cleverley, Jones, Evra, or even Welbeck? I don't think so. And if he was, then it's by a tiny, tiny margin. No, today was a collective failure. There's no point trying to find a scapegoat, when only Rooney and Valencia did well(amongst our midfielders and attackers).
The bottom line is that Kagawa needs much more time. Moyes needs to trust him more, instead of pushing him out to the left wing or take him off the field whenever he's not performing as good as you'd want. Kagawa has shown glimpses of brilliance and done moves Rooney can only dream of doing in his wildest dreams. It's about time Kagawa also gets to finish a couple of games in his best position, even when he's not playing well.
Give him a nice run. If he fails, then so be it. Sell him and try something new.
