Arsenal are playing a nice game in the mean time (first half) , they play as a home side not giving Madrid the chance to gain overall possession of the ball. Madrid defense is a real issue for them in this game. Although both sides have created some crucial goal opportunities but just couldn't make a goal out of those chances. The game could take a different turn with goals in the second half.
Arsenal are indeed playing a good game but the absence of a striker is being really felt because by now the Gunners should have been several goals up if their chances had been buried by a striker. Saka is making good impact but the efforts are going begging and I'm just hoping that they can be calm enough to bury their chances because go be frank Madrid are still finding their feet and aren't even confident enough.
Arsenal can do better in the second half and I believe that if they add more energy to their game, they will surely get a goal from their visitors. For now courtois is being mindful not to make mistake and if Arsenal can capitalize on the defense that's a bit shaky, they will be rewarded.
