The 18-year-old defender is a former Brazil Under-17s international teammate of Lucas Piazon and moves to Stamford Bridge for an undisclosed fee.
An attack-minded right back, the youngster has played only 18 league games for the Brazilian side, having made his senior debut earlier in 2012.
Despite being scheduled to complete the move during the winter window, the fullback will not actually join Chelsea's squad until next summer.
