Well I think Barcelona showed a great football against all teams and despite starting from 2015 they was the fav. they showed a great football and I think they won in a unique way.

Victory against City (epl winners)
Victory against PSG (ligue one winners)
Victory against Bayern (budesliga winners)
Victory against Juventus (serie A winners)

I agree with you that money is buying football but that's how things are, I prefer to have these teams then Ajax or Benfica in a semifinal because I don't want to see another episode like Shaktar - Bayern or Porto - Bayern.
