It is a very tricky game. Indeed, and that's why Arsenal had to give away their Premier League match against Everton for the full preparation of the match against Real Madrid. They know what's really involved in the match, to play against a defending champion. They have to give all their might to win in the first leg because it is as if the Champions League is where their whole hope is, to make a mark in that area since the Premier League is becoming far from their reach to lift it.
Both teams are not playing top-class football these few weeks. Real Madrid lost their last game against a lowly rated team, Valencia, in Santiago Bernabéu. They have a poor defense that has not shown a lack of quality this period maybe due to aging players. They are just lucky that Despite a lengthy investigation, Kylian Mbappe, Vinicius Jr, Antonio Rudiger and Dani Ceballos were all cleared of wrongdoing due to their celebration after they won the round of sixteen matches. Arsenal is also not in good shape, and it showed as they drew in their last game with Everton. But good that Bukayo Saka will be playing game because without him the Gunners is vulnerable.
