Manchester United legend Roy Keane believes the club must do what it can to keep Cristiano Ronaldo.
The Portuguese forward does have another season remaining on his contract with the club.
However, Ronaldo may choose to request a transfer, given United will not be playing Champions League football next term.
Speaking after United's 3-0 win over Brentford on Monday, Keane stated: "It [Ronaldo's signing] was a short-term fix, for the fans, for the share price. But he has still scored the goals.
"Manchester United have bigger problems than Cristiano Ronaldo.
"I just think with the goals that he has got, his performances, warrants staying at the club. But Manchester United have to get players around him, they have to get other strikers in, there has to be competition for places.
"If the leading goalscorer, the man you are depending on, is 37 years of age then that is certainly not good but I would certainly be holding onto Ronaldo.
"There might be a conversation that needs to be had about the way you are going to play or that you are not going to be playing week in and week out. But why would you get rid of a player who scores that many goals? I don't see the logic in it."
