Real Madrid's match schedule has been quite tight lately so Ancelotti must be able to place better tactics in terms of rotating players even though Real Madrid must use their main players during the Madrid derby this weekend but Ancelotti is expected to be able to read his team's situation very well so that all his main players can be fit enough when facing Manchester City in the Champions League play-off match this season. Because both matches are quite important matches for Real Madrid so Ancelotti must have a way to make a more perfect rotation for each of his players.
Both match are actually important and crucial to Real Madrid, if they win Atletico Madrid they go 4 points again above second position, if they draw it will be 2 points above and if they lose they go 2 points behind Atletico Madrid. Worse still, it's not only Atletico Madrid that Real Madrid should be weary of, Barcelona are fast approaching.
The match against Manchester City is also very important because a win at the Etihad will make them put one foot in the Champions League R16. With the injury crises that Real Madrid has right now, it's really going to be tough for them in the upcoming matches.
