Ronaldo's future at Juventus continues to remain uncertain, and the Portuguese international has been linked with a return to Man United this summer.
According to a report by AS last week, both Ronaldo and Man United are keen on a reunion, and that the 36-year-old is willing to take a paycut to join his former side.
But, Neville, who played for Man United from 1992 to 2011 and was Ronaldo's teammate during his stint at the Premier League side, believes the Old Trafford outfit should not re-sign the five-time Ballon d'Or winner.
"Love him but think it’s better to leave the memories where they are," Neville answered on a Twitter Q&A when asked whether Man United should re-sign Ronaldo.
Meanwhile, Ronaldo completed the season as the Serie A top scorer, with the Portuguese bagging 29 goals in the Italian top-flight this campaign. In a season where Juventus finished fourth in the Serie A and were dumped out of the Champions League in the round-of-16, Ronaldo also won the Coppa Italia and Supercoppa Italiana titles with the Old Lady.
Although where he plays next season is far from certain, Ronaldo will have already turned his attention to EURO 2020 as Portugal look to retain the title they won in 2016.
