Colombian youngster Jhoao Rodriguez has returned to Chelsea from his loan spell with Bastia.
The 18-year-old completed his loan move to the Ligue 1 side in the summer but made just five league appearances, and has now returned to Stamford Bridge.
Chelsea made a move to sign the youngster from Deportivo Quindio in 2012, but he is yet to make an appearance for the Blues. He won't return to west London straight away however, but will join up with Colombia's under-20 side for the Sudamericano, which is a youth championship held in South America.
While one youngster is returning to Chelsea another is leaving, with Tomas Kalas joining Middlesbrough to link up with Jose Mourinho's former assistant at Real Madrid, Aitor Karanka at the Riverside.
There is likely to be more ins and outs at Stamford Bridge before the close of the January window, but Jose Mourinho won't be making any big-name signings according to his assistant Steve Holland.
One name linked with the Blues of late is Lionel Messi, but Holland says that deal won't be happening any time soon.
He said: "It's not a decision I personally would make. When you look at the numbers being mentioned around Messi, I would think it's an impossible deal for any club working within the financial fair play rules."
Chelsea take on Newcastle in their first Premier League outing since their surprise 5-3 defeat against Tottenham at White Hart Lane.
