Yes indeed, their salary is indeed very large and we or maybe it's just me who are just ordinary people, think that is a very high salary for an athlete. Because in reality, every individual also has his own lifestyle and problems, which of course more or less these factors will affect their consistency as well.
Well, an example is like an expensive player like Hazard but in the end he's just more on the bench.

Factors like these make me, as an ordinary person, judge that their salaries are no longer reasonable. Also, as time goes by, of course there will be moments where a player breaks the record for the most expensive salary.
But yes, if they can be consistent it's not a problem, but if they can't contribute big to the team then of course it's a big loss.
But about Arsenal and Barcelona on paper they still have a chance to go further but yes, it's not easy and that's if I only consider their big names.

well if the teams have the money I don't see the problem of paying high salaries
sure that if the teams are in economic trouble, then everything changes
they should only spend the money they have
