The team this season has been built to serve Ronaldo; when Ronaldo is not there, the team hasn't a clue to what to do. However the team also hasn't a clue when he's in the team also.
By signing Ronaldo, we basically decided to disrupt the front three of Rashford, Martial, and Greenwood, a front three that had performed well together under Ole. Not only that, Bruno was a much better player behind those front three than Ronaldo and two others.
As a result of the Ronaldo signing...
Martial left because he wasn't getting games anymore. Rashford was shifted to the right wing (his worse position) because Ronaldo was a guaranteed starter upfront. Greenwood (when he was available) was suddenly selfish for not passing to Ronaldo. Bruno's game suffered, Maguires leadership was questioned. The list goes on.
We were a better team last season without Ronaldo. Last season there were clear partnerships and connections in the team. This season there are zero connections. Ronaldo is a big reason for that.
