In a few minutes, these 8 teams that qualified are all good. Arsenal need hard work, they have made new history. But if they meet big teams like Madrid, City, Munich and Barcelona it seems difficult. But I think Arsenal's chances are still wide open. They just have to work hard and be confident for the next game. Actually I didn't expect there to be a final in this phase (a strong team match). This is because I don't like boring finals.
I agree with you talking about the strength and capacity of all the teams that got to qualify for the quarter finals of the champions league, a critical examination into their performance and you will agree that they all didn't have it easy as they all played a some worth rough game to get through to this stage, although they dis scaled through but it was actually their hard work and resilience.
Some of them like Arsenal did faces a team that was presumed before now not to be such that will caused them much problem but after the first leg they understood that in the champions league there's actually no big or small team as any team can actually get to our preform any team at the slightest opportunity given them so underestimating any team in the champions league will only be to your own detriment, port almost caused Arsenal the champions league but they buckled up so did Barcelona and Napoli after the first leg Barcelona became better.
The next stage of the champions league is actually going to be really interesting because all the team in this current stage are so determined to win the champions league, except for Real Madrid who's still got their domestic league to fall back at if they loose the champions league, most of the teams at this stage has got only the champions league as their hope for a trophy especially Barcelona and Dortmund.
