Why did ronaldo leave man utd?

It all came down to that explosive interview he did with Piers Morgan. He publicly criticized the manager, Erik ten Hag, and the club's ownership, saying he felt betrayed. Ronaldo also said he had no respect for the manager, which made his position there pretty much impossible. After those comments went public, his contract was terminated by mutual agreement. It was a messy and abrupt end to his second run at the club, for sure.
