MILAN – This summer Milan completed the signing of Stephan El Shaarawy, who arrived at the Rossoneri last season at the age of 18 years and nine months, and yesterday he shook the hand of 14-year-old Hachim Mastour. Faith in the ability of the youth is rooted in Milan tradition – and not only for the signing of Alexandre Pato, who arrived at Milanello before he had turned 18, in August 2007. It is illuminating to consider what happened in the summer of ’95 when Massimo Ambrosini at 18 years and two months, Patrick Vieira at 19 years and Tomas Locatelli at 19 years arrived together.
