Lazio defender Wallace has officially left the club to join Portuguese side Braga on loan with a reported €5m option to buy.
Wallace moved to Lazio the summer of 2016 from Cruzeiro after two seasons at Monaco.
He played 66 times for the Aquile without establishing himself as a first-team regular, although he did win a Supercoppa and Coppa Italia.
The 23-year-old has also represented Brazil at Under-20 level, as well as picking up a cap for their U23 team.
Wallace previously played for Braga between 2014 and 2016 but failed to make a single appearance.
