Thinking that Madrid will be able to come back is like Thinking that Arsenal will not be playing in this game, I know anything is really possible in football but there are situations that when you look at critically and consider that which is involved you just understand and conclude that certain things are very likely not to happen such as this, Really Madrid need 4 goals to have a proper comeback enough to get them knocking Arsenal out and they need all four goals in one match but again Arsenal has got a better defence than Madrid does so I'm wondering how the magic will be done except if Arsenal gets to suffer red cards or have their key player injured which is almost not happening so it's an almost not possible task for Madrid but let's see, I will never say never because it's not over until it's actually over.
Real Madrid need to finish next quarter final with 3-0 scoreline to take the game to penalty shootouts. If Arsenal score one goal then Real Madrid has to score four goals to take the game to penalty shootouts. If Real Madrid directly want to qualify for semi finals without penalty shootouts then have to finish the scoreline 4-0. I don't think Arsenal will play that bad in next quarter final after giving there best in first leg. From my point of view, it will be worthy to place money on Arsenal for next leg then on Real Madrid.
They will need to get at least 3 goals on aggregate to take the match into extra time or if they need more than that to be sure, so much the better. It's just that for now with the current performance with chaos everywhere for Madrid when looking at the conditions then it is clearly not an easy matter.
They must make the defense better, in addition to the coordination between midfield and attack must also be improved, especially for their strikers who are currently still very hampered where Vini still cannot contribute greatly because of the closed ego he has and Mbappe also although it has been very good but at some moments he also cannot do much.
The second leg is clearly more difficult but they inevitably have to do that because after all at this time for them trying is clearly better and Madrid must find its rhythm again if it really wants the semi-finals even though we know for now the aggregate of 3 goals is not easy because Arsenal is clearly with great confidence.
