Chelsea boss Mauricio Pochettino admits they're yet to finalise plans for Andrey Santos.
The midfielder has returned after his loan with Nottingham Forest was cut short.
Pochettino said, "We will see, we will see. Also, we need to assess the squad for the players who can go on loan.
"We decided to bring him back because he wasn't involved in the squads at Nottingham Forest. He wasn't involved every week.
"It is good for him to come back, assess him and take the best decision for him and the team."
