For Arsenal to face Real Madrid they first need to play well in the group, where they are in second place so far. By the way, they don't have easy opponents and it's not clear whether Arsenal can take first or second place. Because Sevilla and PSV can play well this season. Arsenal have a difficult group, unlike Real Madrid.
Keep insulting Arsenal indirectly because I'm sure they're not even up to Barcelona standards at the present time, considering that the Gunners are struggling to win games. It's hilarious to draw comparisons between Real Madrid and Arsenal. We understand the distinction; Los Blancos is greater than Arsenal in terms of everything, including players and trophies triumphed, and they are considered as the best leading team in the world. Arsenal qualified for the UCL this season, they still got some strength to compete with elite teams down here.
But, if I consider their results in the local league, then surely Arsenal are still a better team compared to Lens, PSV and Sevilla . But even so, I personally wouldn't compare Arsenal to Real Madrid because obviously, they have much different qualities . So yes, if for example you predict Arsenal will meet or play against Real Madrid in the knockout stages then I think the result maybe predictable about a victory for Real Madrid. But apart from that, I personally don't think that far, because of course at this moment it would be more appropriate for Arsenal to stay focused on qualifying for the round of 16, and not care who the opponent will face later.
Arsenal has been very impressive since the start of the season and are still one of the two English Premier League clubs that are yet to suffer defeat in the league since the campaign kicked off. Real Madrid in their own is not just at the top of the Spanish La Liga standings but has also been able to win the two games they've played so far in the UEFA Champions League competition.
That being said, I think Arsenal can if they play at their best are capable of winning against Real Madrid even when it's absolutely clear to every football fan that the Spanish giants are better in terms of quality players and performance.
