Cristiano Ronaldo may have left Manchester United back in 2009, but the Portugal international forward is still dear to the Old Trafford faithful. It was at United that Ronaldo became the star that he is today, and the 32-year-old has seemingly forever been linked with a move back to United. Eight years have passed since Ronaldo left the Red Devils, but every summer, there are suggestions that he could return to the Theatre of Dreams.

This summer is no different, as speculation continues to link Ronaldo with a return to the club where he made his name in world football. It is unlikely to happen, but anything is possible in football. Who would have thought that Paul Pogba would come back to United from Juventus for £89 million, or that Leonardo Bonucci would leave the Italian champions for AC Milan for just £35 million?

Ronaldo has taken his game to a whole new level at Madrid and is the king at the Santiago Bernabeu. The former Sporting Lisbon star’s goalscoring record for Los Blancos is stunning, and his performances in La Liga, the Champions League and the European Championship in recent years have seen him pick up the Ballon d’Or thrice since 2013.

Leaving Madrid for any other club would be a step down, especially as Zinedine Zidane’s side have won the Champions League twice in a row and are the best team on the planet at the moment, but if you are convinced that Ronaldo will leave Madrid and return to United, then you could use Sky Bet's Request a Bet feature, as outlined by tipping site Footy Accumulators, to use the potential move as part of a custom wager.

United's pedigree remains as big as ever despite their struggles since the retirement of Sir Alex Ferguson as the manager. True, on the pitch, things could take time for United to return to their former glory, but there is no doubt that the Red Devils remain the global superpower that they have been since the 1990s. Ronaldo will always have a place in his heart for United, and one day he could return, even if it be for a single season.

However, the big question is whether United should actually make a move for Ronaldo in the coming years. The Portuguese is going strong at 32, and given the way he has modified his game and takes care of himself, he could continue to play at this level for the next three or four years. Ronaldo, though, is human like the rest of us, and he will start to slow down at some point. Would it be worth it for United to bring a player past his prime and in the final years of his career?
