According to The Sun, Ronaldo is contemplating leaving Real 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 £810 million 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.
The Red Devils are certainly sniffing around for the Ballon d'Or finalist, and Ronaldo has expressed interest in the club, including saying that he wants to "come home." Realistically, however, the deal doesn't make sense.
Landing Ronaldo is going to be an expensive move for anyone. According to David Salazar of LatinosPost.com, Ronaldo has a get-out clause of €1 billion, and his transfer costs could rise as high as £122 million.
There are very few teams who would be able to afford this, and it would be a stretch for the Red Devils. There are other teams who could afford him financially, however, including Paris Saint-Germain and his current club, Real Madrid.
Ronaldo does seem to have strong emotional ties to Man U. He certainly has a lot of respect for the club and for manager Sir Alex Ferguson (per Salazar).
It felt very good there, it was like a family. I had six great years there and am still friends with my teammates. 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.
I won't celebrate if I score against United [during the Champions league match in February]. I still speak with Ferguson. I miss him a lot, and I miss Manchester United.
However, can we really expect this emotional attachment to trump the financial issues? Soccer is a business, and players and clubs must make the right decisions for themselves financially.
Even if Ronaldo does want to return and play under Ferguson again, there is the possibility that it could be impossible. According to Salazar, it is "widely believed" that Ferguson is set to retire.
The Red Devils are already dominating the Premier League, and there is simply no need for them to make a monumental deal that may end up hurting the club more than it helps it. In other words: If it ain't broke, don't fix it.
With the Man U team that Ronaldo knew six years ago slowly falling apart and having more financial interest in other clubs, the rumors that he may return to Old Trafford will fall through.
