Xabi Alonso seems to have already established harmony among Real Madrid's players. The only criticism is that they don't score many goals. They're not wrong about that, as their victories are usually those with one goal more. Real Madrid, on the other hand, has accustomed us all to expecting four- or five-goal wins. Of course, even one goal after three points is enough, but if we're talking about the best team in the world, we expect more.
Criticism always comes to a coach, especially if they're the manager of Real Madrid, as this team is one of the most talked about teams worldwide.
Changing circumstances change everything, and the number of goals isn't really the issue, but rather how to consistently win.
Although we've seen Real Madrid consistently win by a much higher scoreline under Ancelotti, this doesn't mean much; it will take several big matches to see how consistent Real Madrid can be in achieving better results.
