Real Madrid always have confidence in Champions League competition because of the experience they have; right now they are doing better in the Champions League compared to Arsenal.
Arsenal next champions league match will be against Real Madrid, seriously the match is going to be a interesting and tough one, but from the way the two teams are playing, we can see that Real Madrid performance is just better than Arsenal performance, and when it’s comes to the champions league, Real Madrid are always having confidence in themselves, they will wan to get a win in their match, and since saka went on injury, Arsenal performance has dropped, Saka absence is really affecting Arsenal, and I don’t think they can get a win against Real Madrid.
I think Bukayo Saka is back but even if he is back he won't play like he use to because he just got back if at all they will use him and even if they used him there are people who can hold him down. And at this stage Real Madrid has gotten to I don't think it will be easy for any team or club to knock them out because there experience here is mad whether inform or not and even if it was Barcelona they are playing with in this stage I doubt if Barcelona will defeat them despite the form because champions league is Real Madrid thing I mean is like what they do for a living and Arsenal is too small to challenge them though they can try.
