The Red Devils currently sit six points adrift of the top four heading into Sunday's big clash against Chelsea at Stamford Bridge.
Ole Gunnar Solskjaer has already lost his job after United's poor start to the season, but former Arsenal striker Paul Merson feels Ronaldo could also leave if the club finish outside the top four.
"Manchester United needing an interim manager is a shambles - and Cristiano Ronaldo might decide to walk away in the summer," Merson wrote in his coloumn for Daily Star.
"He won't be hanging around if they don't finish in the top four because he will want to end his career in the Champions League.
"And that doesn't look terribly likely right now because United are a mess and will probably get thrashed by Chelsea this weekend.
"It might actually suit all parties if he leaves anyway because if they appoint Mauricio Pochettino and he wants to press from the front, you're not doing that with Ronaldo.
"But what I really don't get is why the biggest club in the world needs an INTERIM manager."
