Robinio Vaz hopes to play at Hull City
It was decided to send him out on loan after just one goal scored and two assists in 14 competitive appearances for the Giallorossi.
Throughout his experience at the Stadio Olimpico, Vaz did not start a single match, garnering a total of 313 minutes on the pitch.

Vaz has joined Hull City on loan for a reported €2m fee, with an option to buy at the end of the season for another €30m.
The French talent is only 19 years old and had impressed in his few performances for Olympique Marseille, scoring four goals with two assists in his 14 Ligue 1 appearances last season before the move to Roma.
