It's a problem you see a lot when a team changes too many pieces at once - the guys can be good individually but they're not playing together, it's like nobody really understands what's expected of them on the pitch. I've got a friend who follows a lower division team, they did the same thing two years ago, threw money everywhere, and for months it was a complete mess because the coach was trying to get everyone sorted but the tactical setup was changing every week. And you can't forget there's also a psychological thing - the fans are putting pressure on the team, the media's screaming everywhere, and that weighs heavy when things aren't working. Give them time, but not too much either, there's a limit before it becomes really serious.
