Playing more defensively and strengthening the defense line as well as building and gathering players in the defense area is a must for Arsenal, because their opponent is Real Madrid who is known to be able to make a comeback even though they are in a disadvantageous position in the first leg because they suffered a big defeat and that always happens and this is what Mikel Arteta must think about and plan very carefully.
However, I am sure Mikel Arteta already knows and plans everything and will also motivate the players to play very carefully and also focus on paying attention to Real Madrid's attackers to continue to put pressure because pressure is something that can make it difficult for attackers to penetrate the defense to be able to score goals. And if you look at their current performance, I am optimistic that Arsenal can maintain their advantage even though Real Madrid won this match but the aggregate victory remains on Arsenal's side, because 3 goals without reply in the first leg is a very good provision.
Am not a magician, but if arsenal came to play this reverse fixture with this kind of defensive mindset, they are going to lose and crash out of this year uefa champions league because they will be unable to hold unto their lead, it's true that three goals look very big in our eyes, but if they decide to play with such inferior mindset, they will definitely going to regret their actions because this is real madrid, they can't scale through by feeling or playing with inferiority complex, I expect arsenal to play their normal game just as they played at the Emirates stadium, because that is actually the best way they can progress to the next stage of the competition, though at some point in the game they might decide to be defensive and preserve their lead, but being too defensive from the very first minutes will do them quite a lot of harm than good, but if for any reason arsenal lost and get knocked out in this contest, I will take them as the most stupid and the most unreliable football club of all time.
