If his team was losing and he did this, it would still be wrong but at that point, I would understand that. In spite of this, his team is winning and there was no need to do this. It is only meant to have a negative impact on his career. It is going to be a lot more difficult for him now, from my point of view, to find suitable teams in the future.
Well, i for one also think that Ronaldo has been constantly disrespected by Manchester United and Erik Ten Hag, but the team is always bigger than a single player, and despite the fact that Ronaldo is one of the greatest player's of all time, he still has to respect the club in all ways possible. Shortly after his suspension from the team, Ronaldo has issued an official statement/apology to the club, and from his words i think he is really sorry for his actions and the club should forgive him and the two parties should work together and show each other more respect going forward, at least before he maybe leaves in January.
