Some seasons, Ronaldo used to have a slow start. I remember even the media will be trolling him and he will be pained. But at a time he will turn around his performance and start scoring goals.
Why he hasn't picked till now is because he has not gotten enough playing time. If Erik gives him some more playing time, he will find his form and happiness again.
We always expect good performances from players like Ronaldo. But the performance of a legendary player like him has been very poor this season. Ten Hag is not using Ronaldo correctly. Ronaldo is not in Ten Hag's match plan. Ronaldo is unable to adapt himself to the team. And I don't think he's getting any help from coach Ten Hag. And so we see Ronaldo's poor performance in every match.
It is true that Ronaldo is not in the plan of Manchester United coach. The coach is playing normal football where the number nine player will be the one that will counter-attack and press the football, this is what Ronaldo will not do well due to his age, he cannot do that kind of work that is expected of him by Eric . That is why he normally comes from bench. If Eric is to incorporate Ronaldo into the Manchester United team he should reverse to 4-3-3 formation, with 4-3-3 formation, Ronaldo can find his place in the squad either from the left-wing or at the centre of the three
