Real Madrid could indeed win in the 2nd leg because they will definitely take revenge and they will also be more enthusiastic because they are playing at the Santiago Bernabeu but yes it is true of course even if Real Madrid wins I also predict that Real Madrid will not be able to advance to the semifinals because of course it is not easy to score many goals for Real Madrid against Arsenal. moreover Arteta will certainly not remain silent even though they visit Real Madrid's headquarters and of course Arteta will make his best strategy to win.
What if the match ends in a draw and goes to penalties?The game hasn't started yet and anything can happen as Madrid have a good plan to score 3 goals and defend until the end of the game. If Madrid manage to end up in the penalty shootout, I believe Madrid have a great chance.

but on google I see Real Madrid is favored in that match but of course if I will favor Arsenal's victory because I have a feeling Arsenal will win.
Favour Arsenal to win the match or favour Arsenal to qualify to the semi finals? Even if Madrid win the match by less than 3 goals, Arsenal will still qualify for the semi finals.So, betting on Arsenal to win is high risk for me.
