Nothing is to blame, Liverpool are just a better team right now. It's really that simple.
We're coming to the end of a 3-4 year cycle which will see our established old guard in Kompany, Fernandinho, Silva and Aguero leaving to be slowly replaced by Ederson, Laporte, Bernardo, De Bruyne and Sterling. We just need to be patient and let those players slowly establish themselves as the new leadership team and move on.
Liverpool's front three, Alison, VVD, Matip, Robertson, Fabinho, Chamberlain, Henderson, Shaqiri, Wijnaldum are all 27-30, they've bought players who have all come into the peak of their careers together and are seeing the benefits. It won't last, because it can't, in 2-3 years time they'll have to start replacing a lot of players over a short period of time. The younger players in the squad are Trent AA and Joe Gomez, some young lad with a stupid haircut whose name escapes me and that's it.
