The out-of-favour Giallorossi left-back is hoping for a fresh start at the Anoeta, after completing a temporary switch to the Primera Division club
The 22-year-old found first-team appearances few and far between in his first season in Serie A, and with new boss Zdenek Zeman unable to offer guarantees of regular action, he has opted to make a return to the Primera Division.
The Basque club have the option to make the move permanent at the end of the season, and Jose Angel is excited by the challenge ahead.
"For me, coming to La Real is not to step back, I have come to a big club," he told Mundo Deportivo.
"Roma are a very powerful club, but there were few opportunities for me there. To come here is not a setback, sometimes in football you have to take a step back to take another one forward."
Other notable clubs were also rumoured to have shown an interest in the former Sporting Gijon man, but with no firm offer on the table, Jose Angel says his decision to join the club was an easy one to make.
"Valencia and Benfica showed an interest but remained just that, an interest," he added.
"At the end of the day, to make a decision I have to see the effort each club puts in and Real Sociedad made a big effort to acquire my services."
