Especially for Paris Saint Germain, I feel they are now more even, they no longer rely on one player which I think is one of the things that makes them play better this season and can be here.
When a team only makes one player the mainstay then they will be easier to read. And this season Paris Saint Germain can be more collective in the game so that makes it more difficult for other teams. For example when they still have Mbappe, when they play almost most of their goals are Mbappe in the front line.
I love that part where you said they no longer rely on one player which actually makes them more deadly. Yeah, when a team is like this where they don't rely on single player to make or get the goals for them, they become so unpredictable because when you think you're marking a particular player out another steps up in his place. Against Aston Villa, in both legs Dembele didn't get a single goal, it was only two forwards that scored in the entire two legs which is Kvaratskhelia and Doué. PSG scored a total of 5 goals across two legs and 3 of those goals were scored by two different defenders. That's what makes them dangerous.
