Arsenal manager Arsene Wenger admits Cesc Fabregas is "very impatient" to return to action but insists the midfielder will not be rushed back too soon.
The 20-year-old has been sidelined by a hamstring problem since limping out of the Champions League clash in Sevilla on 27th November.
The Spaniard has already missed matches at Aston Villa, Newcastle and Middlesbrough, while he will also sit out the final Champions League Group H game with Steaua Bucharest at Emirates Stadium on Wednesday.
Wenger revealed there was no guarantee his star man would be back for the visit of Premier League title rivals Chelsea on Sunday either.
"We haven't set any date for his return yet," said the Arsenal manager.
"Cesc is not with the group at all; he is with the medical people being treated. He is working very hard.
"Cesc is very impatient, but he is not back yet."
As well as Fabregas, Arsenal have several other players still on the treatment table, including Alex Hleb and Mathieu Flamini.
