Hey Madrid what happened to you?

As a Real Madrid fan of course I am very disappointed with their performance this season especially in the Champions League recently they have not played like in previous years which were very tough and were strong candidates to win the title but it seems like this season they are in trouble with the quality of their game declining even I didn't expect them to lose to AC Milan who have been playing badly lately this defeat is the second painful defeat after their defeat against Barcelona at home.
Vinicius, Mbappe and Bellingham seem to have not found the right chemistry to be able to work together well.
Last season too we saw Madrid win all their Champions League group stage matches to qualify for the next round. But this season, Madrid's performance is not as good as expected. Real Madrid have lost two of their first four matches. And right now Real Madrid is in 17th position in the points table. There is no doubt that Real Madrid are very experienced on the Champions League platform. However, Real Madrid is not able to perform well this season.
It was unthinkable that Real Madrid would perform so poorly against AC Milan. Real Madrid defenders are not able to play well. At the same time the attacking players are not able to score goals despite attacking a lot. I would say Ancelotti should change his match tactics.
