Can't guess how Arsenal will play later --- whether to play defense or more to attack like in the first leg, but if Arsenal's game is suppressed then the possibility of Arteta's strategy could be defensive all the time, because Real Madrid's way to win will be very wild to continue to attack Arsenal's defense.
I think 70% of Arsenal is very safe because they are 3 goals ahead in the first leg so in the second leg Arteta only needs to arrange a more ideal formation to defend against the host's attacks. Automatically Real Madrid will not play casually, they will definitely attack from the first minute so Arsenal's defense wall must be really strong to be able to stop the attacks carried out by Real Madrid.
If Arsenal manages to eliminate Real Madrid, all fans will be quite happy because beating Real Madrid in the Champions League is so difficult. For that, in the second leg Arsenal must play more carefully because they have a better chance in the Champions League compared to their hopes in the Premier League.
