Arsenal is not a team anyone will see and believe that they can stop Real Madrid from winning the competition. Maybe if they meet in a more intense round they will try to win. In football, not everyone can be looked down on, so I won’t say Arsenal can’t do it if they try. The priority of Arsenal might be the premier league but I think they’ll also try their best in the champions league since they’re already there and won’t want to be exited from the competition with disgrace. As it stands, the best teams still remain Manchester City and Real Madrid as you said, we expect a more tougher competition, so I hope more teams will show more improvement when the competition begins.
Arsenal today is not the same as the Arsenal we knew before, currently Arsenal performance has improved drastically and has even been able to provide strong resistance to their opponents in the Premier League so far, but if we talk about the Champions League of course they are still not able enough to provide what the fans expect today, Although Arsenal are on the right track at the moment with Arteta, to be honest, I will not try to bet on their chances of winning the Champions League next season, although currently there are many predictions that favor Arsenal to be able to compete in the Champions League, but I think this is very unreasonable at all because indeed their mentality and quality are not ready to compete with other European teams.
As long as I watched football, the first time I saw Madrid vs Arsenal face off was in the Champions League in 2006, where at that time Arsenal managed to beat Los Galaticos which was filled with many star players, but after that match I no longer saw Arsenal facing Madrid except in a friendly match, of course it is quite interesting if later the two teams will meet again in the Champions League and I think it will repeat the nostalgia we as football fans in the golden era of Arsenal with The Invincible and also Madrid with Los galaticos.
