Does that mean a club like Arsenal is not suited to winning big? Every club that participates in the Champions League has the same ambition, they will do their best and those who can be consistent until the end deserve to win. Arsenal has no doubt they have reached their best level in the last few seasons and will continue like that if Mikel Arteta is still at this club, I think they will definitely get one of our prestigious trophies, it's just a matter of time.
Prestigious trophies are earned by hardworking clubs, especially the ones that have gain consistency in league games. Following in illustration of Pep Guardiola and Carlo Ancelotti. These are the main managers of elite trophies, if your club wants to lift a major cup, tell the team's board to make signings of these experience managers that are capable of surviving in all soiling clubs. It's better we acknowledge the fact that these managers have priorities and visions for only elite clubs and holding on with appropriate instruments. Every UEFA elite club have priorities to meet up and they're basically hitting harder than never before.
It's not about handwork but I will agree with you that consistency is what will make a club win the Champions league trophy. Having a good performance today and in the next match day they fall low in performance. Inconsistency will never allow a team to win such trophy. And that is what differentiate clubs like Manchester City and Real Madrid to Arsenal, Bayern Munich ad PSG. I am not saying that Arsenal Bayern and PSG did not have good performance in the last UCL competition but am saying they are not strong currently to maintain that winning streak among all teams they face.
