Maybe.
The evolution of this team seems to be from experience rather than ability. I'm not sure that the three named players were so bad that they would have dragged us down. We have achieved plenty with them in our ranks.
However, you could argue that Sterling was on a downward trajectory, meaning that he would've become a deadweight of sorts.
More significantly, you could argue that if we kept Zinchenko, we never would've had a need to go to the 4 CBs strategy, meaning we might not have had the tools to win anything this year.
Assuming Alvarez would still be here, I don't think Jesus would've had a negative impact still being here.
