Still don't think they'll win any major honors this year but in time, Moyes will come good. As for Kagawa, he just played a friendly in Japan like three days ago, so maybe Moyes thought that wouldn't be the best way for him to play. He was amazing for Dortmund and he should be amazing for Man U, unless he's another Sahin. (Who by the way seems like he's getting back to be amazing for Dortmund, and even took a paycut to go there)
Edit: I can't believe Giggs still plays this much. He really doesn't bring much to the team at this point. He's afraid to shoot and, I don't know I just don't see his purpose on the field. Especially with other options like Rooney and Kagawa available. I also originally thought Giggs made a brilliant assist on the opening goal, but it was a total deflection, he didn't mean to play it that way. Welbeck was good but he also gave the ball away for the Swansea goal.
One more thing, what is it with the English constantly badmouthing the good players that you have? You may not be the best footballing country in the world, but a guy like Rooney is legitimately good. He's a fairly complete player and can play a number of roles brilliantly. Welbeck, Jones, Kyle Walker, they're all very good young players who take stick but are really good.
