According to Anthony Kastrinakis of The Sun, the forward is considering leaving his current club after not receiving a new deal:
Cristiano Ronaldo has waited 11 months for Real Madrid to give him a new deal—now he can force his way out in the summer. Just like he did when he was at Manchester United.
His £810million get-out clause gives Madrid the upper hand. Or does it? This summer, Ronaldo will have two years left on his contract. Snub a new deal and, get-out clause or not, Madrid will have to accept a much lower fee.
If he were to leave, there would be no better destination than right back at Old Trafford.
From 2003-09, there were few better matches than Ronaldo and Manchester United. The elite scorer helped his squad win three Premier League titles, two League Cups and the Champions League titles.
In his last two years, he really showed his ability on offense with 68 total goals.
Since leaving, he has continued to be one of the best players in the world. He and Lionel Messi continually go back and forth on the pitch and in the record books in the battle to be the sport's best.
However, the record £80 million move to Real has not changed his positive opinion on his former team.
According to Manu Sainz of AS.com, Ronaldo had some kind words for the club he is set to face in the next round of the Champions League:
I won't celebrate if I score against United. I still speak with Ferguson. I miss him a lot, and I miss Manchester United. I felt very good there, it was like a family. I had six great years there and am still friends with my team-mates. It is thanks to Manchester United that I am here playing for Real Madrid. Without them, I wouldn't be the player I am today.
The fact that he misses Manchester United bodes well for the prospect of the two sides reuniting.
Between Wayne Rooney, Javier Hernandez, Danny Welbeck and newest addition Robin van Persie, the club has little need for offense. In fact, Manchester United is currently on top of the league table thanks mostly to its league-leading 44 goals scored.
However, you can never have too much scoring in this sport. This is especially true when playing some of the tougher opponents in Champions League.
Last season, Real Madrid was able to win La Liga with 100 points in 38 games. The squad scored 121 goals, which was enough to best Barcelona and more than twice as many as third-place Valencia.
Should Manchester United go after Cristiano Ronaldo?
It might be difficult at first to get everyone to play together, but Rooney and van Persie proved this year that two top players can co-exist.
In Kastrinakis' article, he states that a transfer for the star would cost around £122 million. While this is quite a bit of money, he is one of few players that would be worth it.
Ronaldo could instantly turn Manchester United from great to nearly unstoppable. For everyone associated with this club from the players to the fans, this is something they should strive to achieve.
Sir Alex Ferguson should do whatever it takes to get his man back where he belongs.
