The EPL has improved in the CL the last two seasons, prior to that they wer in a funk since wining it in 2012.
Inter blew it, Napoli's defense conceded too many goals, Roma snuck in by the back door and Juve got lazy. After Mo Salah made Mario Rui look like something out of a Monty Python football game, I don't expect him to around long. Liverpool has benefited bigly by signing Roma players. The EPL has the money, after Brexit that may change.
Roma fans can't ask for much more than James Palotta has given, they desperately need a new stadium to seriously compete in the CL.
