The Champions League title is almost everything for Madrid, they'll fight it even if they have to sacrifice another league for their purpose. Ancelotti is a very experienced coach in that situation. He will willing to ignore any league in order to strengthen its strategy. he keeps his ultimate strategy for the summit match. he keeps it so, that no one will know when Real Madrid playing in the finals. I think Arteta knows that, he shouldn't underestimate Ancelotti and be careful to deal with him. So far, Arsenal is not favorite on this situation based on what they did on premier league, while Real Madrid, everyone know, they squad was filling up football stars on the world which can be mission impossible for Arsenal go to next stage.
Madrid are experts when it comes to the Champions League they have experience more than any other person, but even with their experience, it does not fully guarantee that they will win the Champions League, just that they are also in very good condition too, and Ancelotti is the man behind everything that is currently happening, and he as stayed for some time now with Real Madrid, and I love the fact about him that he is always ready to risk everything about the Champions League because this is not the first time that he will take the La Liga for the Champions League, and this is something that for sure Barcelona cannot do. and Arteta already should have known what Ancelotti is capable of doing when it comes to the Champions League, and I am surprised that Arsenal have even gone this far because we know how Arsenal can be full of shit. everyone already knows that Arsenal cannot make it to the next stage, but they will just have to perform even if they do not get there.
