Brazilian right-back Wallace has joined Inter Milan on a one-year loan deal from Chelsea.
Wallace passed a medical at the San Siro Tuesday and will stay at the Italian Serie A club until next June, according to Globesporte.
The 19-year-old signed with Chelsea last December but remained with Brazilian club Fluminense until June.
He made his debut for the London outfit last month in an 1-0 pre-season friendly victory over Singha All Stars in Bangkok.
