Manchester United striker Radamel Falcao has sparked fresh transfer speculation on social media. The Mirror reports Falcao has fuelled speculation of a summer switch to Real Madrid after following the European giants on Twitter.

The 29-year-old has managed just four goals in 22 games for Manchester United since arriving on loan from AS Monaco on deadline day.

United are unlikely to trigger the £42.3million buyout clause in the deal, with Real among the sides believed to be in the running to sign him at the end of the season.

And Falcao has intensified speculation that he could be on his way to the Bernabeu after following them on the social networking site.
