I didn't say that. But we are not losing due to our best players. They are not part of the problem, they are part of the solution.
The issues that we have are with the bottom 3rd of the squad. Just not good enough
I agree, but even Real Madrid is dependent on Benzema making solid offensive contributions. PSG is dependent on Neymar and Mbappe creating an imbalance in the opposing team. That's what star players do. Creating an imbalance in the opponent's last third is extremely difficult, and to achieve this you usually have to have very good individual players.
This is where we see the greatness of JR. How he finds the rooms with his passes. DCL is more of a finisher than a creator. He is very good in the penalty area, but has very little to offer outside the 16-meter.
Richarlison I'm more uncertain. He has good all-round skills, but is not very creative, or fast, does not have particularly good passes / crosses, and does not impress very much in 1 vs. 1 situations. However, he has had an ability to score goals, which is the most important thing in football. When he does not score goals, he appears as a very ordinary football player.
