Fabregas, Alexander Hleb and Mathieu Flamini all trained yesterday and are in contention to return to the Arsenal side for Sunday's clash against Chelsea.
Arsene Wenger will leave it as late as possible to decide whether they will make the starting line-up but is keen to recall Fabregas.
Wenger said: "They are back in training, some of them for the first time since being injured. For everybody I will leave it as late as possible to make a decision.
"That means Sunday morning. We have to assess the whole situation, who can start, who can last and who is completely fit."
Wenger would like all three available for the match against Arsenal's bitter rivals.
"You would like a team you feel is ideal to play. If Fabregas is fit he will play," he said.
