The 18-year-old joined Real Madrid from River Plate for a reported £60 million, but found first team opportunities hard to come by, especially following Xabi Alonso’s exit.
Mastantuono started just 11 of his 23 LaLiga games, scoring one goal as Real Madrid finished in second, eight points off Barcelona.
According to Spanish outlet Fichajes, Mastantuono is facing a critical few weeks as Real Madrid decide what to do with him.
It’s understood that Cesc Fabregas’ Como are keen on signing him on loan with former manager Alvaro Arbeloa looking to bring him to new club Fulham.
Real Madrid would prefer to send him to Como following the immense success of Nico Paz’s time under Fabregas.
