The future of Cristiano Ronaldo remains a constant source of speculation in Spain, with some reports earlier in the week suggesting the Portuguese winger was open to a move back to the Premier League.
Reports in The Daily Express claimed the £80 million-man has become disillusioned with life at the Santiago Bernabeu, with jeers from supporters adding fuel to the fire over the player's future.
Why Madrid fans are so upset with Ronaldo remains up for debate, and is a topic GiveMeFootball tried to understand on Monday. Sitting seven points clear in La Liga and progressing well in the Champions League, Los Blancos appear to be on the right track.
Despite proving to be the focal point of most positives in the capital, Ronaldo's application has fallen foul with some of the locals, with the boo boys not exactly inocuous on any given match-day.
It's led to the obvious suggestion that a Manchester United return could be on the cards, with both the player and former manager Sir Alex Ferguson admitting their respect for each other following the summer 2009 switch.
Whilst, in the short-term, a return to Old Trafford would seem like the best possible move for all parties (the Red Devils at least), you can actually argue that it would be detramental to both parties.
No, before you say it, I'm not crazy. And no, I'm not a Manchester United fan. I don't support any of the other 'big' teams in England, Italy, Spain, Holland or Germany either, so my claims don't hold an alterior motive.
The philosophy is simple in the theory that United are now bringing through some of England's best young talent. Whilst some of the old guard remain (Giggs and Scholes), the attacking-line is built on youngsters who look to spread the burden.
With Ronaldo in the side, United became reliant on the former Sporting Lisbon starlet. True, he often delivered, and during his time at Old Trafford he won three Premier League and one European title.
But things are different now. Wayne Rooney is a better player leading the line, Ashley Young is one of England's best wingers when fit, and the future looks very bright with Tom Cleverley and Danny Welbeck becoming first team regulars.
Who would miss out if Ronaldo returned? More importantly, would he be willing to play a team game and fit in at United?
Generally used on the wing, Ronaldo would have to play in a more defensive role to meet the requirement of a 4-4-2 formation currently utilised by Ferguson, or lead the line up-front alongside Rooney. That would also push Javier Hernandez and Dimitar Berbatov further down the pecking order.
It's European glory that United fans crave most though, with Ferguson's two successes in 25 years arguably a failure, given the domination the club enjoyed in Engand over the past two decades.
Ronaldo can't guarantee that. Madrid drafted Ronaldo in to held leap-frog Barcelona domestically. Up until this season, it hasn't happened. And, whilst Madrid are leading La Liga, they haven't beaten Pep Guardiola's side in three meetings this season.
Why he would be able to achieve success with United after failing under 'the Special One' is again up for debate. That Barcelona raise their game when playing Madrid is one reason, but they wouldn't take United lightly if they met in next season's Champions League semi-final, for example.
Financially, iy would also take a huge sum to get Romaldo back to the club. Probably not £80 million, but that money has since been invested in other players, with the likes of David de Gea, Phil Jones and Young not exactly arriving on the cheap in recent windows.
Spending big on Ronaldo would also end hope of signing Wesley Sneijder. If United need a player in any position, it's attaacking midfield. The Dutch playmaker appears to be the perfect choice, but spending what would be in the region of £100 million on two players isn't the way United do business.
If you could take Sneijder for £30 million or Ronaldo for £60 million; which would make sense to you? It has to be the Inter Milan man for my money.
And then there is Ronaldo himself. Would a return to Manchester United add to his global powers, or would he simply be treading old ground in-terms of fans and followers on social media websites and commercial endorsements.
As David Beckham has proved in the past, expanding the brand across Europe is a great way to increase your marketability. I'm not saying move to America, but a different club means new supporters.
In short, the move would be a quick fix to perceived problems that have come from being knocked out of the Champions League early.
Winning the Premier League is harder now than in years gone by because, in simple terms, Manchester City have spent billions of pounds in an effort to bring success to the Etihad Stadium.
That doesn't mean things are wrong at United, and Fergie isn't one to make a sudden move in the transfer market. Ronaldo isn't the man for Manchester at the end of the season.
