Basically Ronaldo is no longer comfortable at Manchester United, for that reason I personally don't believe Ronaldo will give everything he can to make Manchester United rise. At least there is still time until the end of the month for Ronaldo to leave, because for me it will only be useless if Ronaldo is maintained and played from the early minutes because here Ronaldo doesn't seem to have any targets. So yes, even so, Erik ten Hag must continue to make Ronaldo the main player, because it is not appropriate for Ronaldo to be treated as in that match.
Ronaldo is crazy (in a good way) and he will try his best in any situation. But it will be better for him and for the club if he comes out from the first minutes of the game - even in the first round without him the team played 0-2, and with him (although he did not score) 1-0. In terms of comfort, it's hard to find a player at United who feels good these days
And yes, I think Ronaldo will leave United before the end of the month.
