Chelsea are able to welcome back both Estevao and Liam Delap for the visit of Aston Villa on December 27.
Delap has been out with a shoulder injury which he sustained in the 0-0 draw at Bournemouth earlier in December, while fellow summer recruit Estevao has been out with a “small muscular problem” that saw him miss the 3-1 win at Cardiff last week.
Enzo Maresca previously suggested the pair were in contention to face Aston Villa after Christmas, and has now confirmed the good news.
“[Estevao] is back. He is available for Saturday,” Maresca told reporters on Wednesday.
“And also Liam Delap, he is available for Saturday."
There is still no sign of a return for Romeo Lavia, Dario Essugo and Levi Colwill, who are longer-term absentees.
Chelsea face a daunting task of stopping Villa, who have won 10 games in a row across all competitions.
After a troublesome start, Villa are now firmly in the Premier League title race having built up a seven-point gap over fourth-placed Chelsea.
“They are doing fantastic,” Maresca said on Villa. “They are doing fantastic this season, last season, years ago with Unai [Emery]. They are doing a fantastic job.
“As you said, at this moment they have won 10 games in a row. Hopefully we can win the game on Saturday."
