It's explained by the fact that the overall standard of European football right now has fallen off a cliff. Real Madrid and Barcelona aren't remotely at previous levels when Guardiola, Mourinho, Luis Enrique, Zidane, and Ancelotti were at the helm. Bayern, with few top-class German internationals (because German football is in the toilet), are flat-track bullies who will be found out in the last 8. There's no Klopp figure doing bits at another German club. Italian football fell off a cliff 15 years ago and hasn't recovered. We're a long way from the days of Lippi's Juventus, Capello's Milan, or Paolo Maldini now. PSG are an artificial construct. French football is in the gutter.
That said, many of the English sides will hit a wall when they play some of the above in the knockouts. The stresses and strains of the financially doped Premier League always exact a toll.
