I think the Spanish Super Cup final was also an important match for Real Madrid, but their performance was far from expectations. Even though Man City is in a bad period, it doesn't mean they can win the match easily, especially before this match takes place, Madrid has to face Atletico in the continuation of La Liga. Real Madrid performance depends on the strategy carried out by Ancelotti because the players' energy will be drained in the Madrid Derby to fight for first place.
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.
I hope that Real Madrid should be able to get a win in the Madrid derby this week, and also beat Manchestter City in the Champions league match, looking at Man City I think they can get a win against Man City who are not in good shape, but Man City will also do hard work to get a win because they are also not in a safe condition, it will be difficult because their time is close together so it is very important that there are no games that bring injuries to Real Madrid players so that they can go through these two matches perfectly and Real Madrid can get a win.
Neither Madrid are in a safe space, they have lot's of injured first eleven players. I don't know what to expect from the match, both teams were never been up in their games for a while now, giving Madrid the lead over City still doesn't do justice to Pep and his team. The match will be tough more than what we City faced against Arsenal, the score line will be hectic for any of them, who would be the lucky on that day no one can tell, but yet Manchester City are definitely going to put up the best performance, Manchester City could just be the right team for the victory on that day.
For the derby, they can be fortunate but same problem with the available squad they may not be fortunate aswell, we saw what happened against Leganes, it was a close game that almost ended draw. Atlético are also starving for same points, knowing their weakness at the moment puts Real Madrid in a big disadvantage.
