All possibilities of winning are possible but we are realistic that this will be very difficult for Arsenal, especially as we know that Real Madrid has different energy and strength when playing in the Champion League competition because they have a fairly high mentality and that is in contrast to Arsenal, especially Arsenal's performance this season is not so good with a series of bad results they received in the Premier League so I think this will be very difficult for Arsenal and I do not believe in the big surprise that Arsenal can give, remember that Real Madrid is the king of the Champion League.
The Champions League is very competitive. And here we have to be ready to see any result. Every team is very strong. There is no other team as experienced as Madrid in the Champions League. However Arsenal cannot be called weak either. Arsenal has the full ability to defeat Madrid. That is why this match is going to be one of the most competitive matches in the quarter-finals.
Arsenal has no chance of winning the Premier league title. So Arsenal will probably focus completely on the Champions League now. On the other hand, Real madrid is fighting for the La Liga, Champions League and Copa del Rey titles. Real Madrid has a very busy schedule. Because of this, I will not be surprised if Madrid's performance is a bit irregular.
The first match is Arsenal's home match. If arsenal can play well at home, then maybe Arsenal will have a small chance of qualifying for the semi-finals. But if Arsenal can't win at home, they can't win at the Bernabeu.
