Manchester United striker Radamel Falcao sparked wild speculation on Sunday by following Real Madrid on Twitter, before swiftly unfollowing the reigning European champions.
This is according to the Manchester Evening News, who speculate that Falcao's decision to follow Los Blancos could be the "strongest hint" yet that he will leave Old Trafford at the end of the season.
Falcao, 29, is expected to leave Manchester United when his season-long loan deal expires at the end of the season, while his parent club AS Monaco will cash in provided an interested club meets their £43.5 million asking price.
Clubs interested in signing Falcao on loan
A host of top clubs are reportedly keen on Falcao, but none appear prepared to pay a fee to sign the Colombia international on a permanent deal.
It's understood that the likes of Chelsea, Liverpool and Juventus are all considering Falcao as a potential loan option when the transfer window re-opens this summer.
Florentino Perez is a fan
Real Madrid have not been linked with the former FC Porto and Atletico Madrid superstar in recent months, but were strongly rumoured to have had an interest in the South American ace in the days before his surprise move to Old Trafford.
Florentino Perez, Real Madrid's current president, is known to be a keen admirer of Falcao, who appeared to believe he had secured a move to the Bernabeu last August.
Second Real Madrid gaffe on Twitter
Falcao prematurely confirmed his move to Real Madrid - once again on Twitter - by posting the message: "Dream come true #HalaMadrid".
Like Sunday's tweet, that particularly post was quickly deleted, but not before hundreds of screenshots had gone viral on social media.
Two days later Falcao completed an unexpected loan move to Manchester United; but he has flatted to deceive since joining the Red Devils, scoring a pitiful four goals in 19 appearances.
Real Madrid are better off without Falcao
Aside from Perez's admiration for the striker, quite why Real Madrid would want Falcao is a little mystifying.
Crisitano Ronaldo is still scoring goals for fun, Karim Benzema remains one of the best - if not underrated - centre-forwards in world football, while the promising Jesé Rodríguez is a young striker with immense talent.
Javier Hernandez will leave the Bernabeu this summer, and Perez might be looking at Falcao to fill the gap left by the Mexico international - but whether the Colombian could rediscover his best form in Spain is doubtful.
The serious knee injury he suffered in January 2014 - which forced him to miss last summer's World Cup finals in Brazil - has hampered Falcao, who has looked a shadow of the striker who tore up La Liga with Atleti.
But Falcao proved last week that he still has an eye for goal, netting twice in Colombia's emphatic 6-0 victory over Bahrain.
