During the rest day at the Giro d'Italia, a debate raged on social networks. Greg Henderson, the Lotto Soudal rider, tweeted last month his remarks on Thursday evening, saying Aru, who finished third in the 2014 Giro d’Italia at just 23-years-old, should come back clean or not come back at all. Even if Henderson apologised on Twitter after claiming Fabio Aru's current illness is a cover for biological passport issues, the Astana rider will take legal action against him.

"With regard to the quotes of Greg Henderson posted on his Twitter profile on April 25th 2015, Fabio Aru empowered his attorney Avv. Napoleone to take legal action against the New Zealander pro cyclist in order to defend his image and his respectability", Aru’s agent Alex Carera explained in a press released. Carera and Aru’s lawyer Giuseppe Napoleone it was announced that the defamation legal action was “undertaken to protect the good name and integrity of the cyclist Fabio Aru."
