Defender Laurent Koscielny and midfielders Mikel Arteta and Mathieu Flamini could all return for Arsenal against Watford on Saturday Night Football.
Koscielny and Flamini have been struggling with hamstring problems and both missed the Premier League win over Manchester United last time out.
Koscielny has not played since the Champions League defeat at home to Olympiakos while Flamini has not featured since the the victory at Leicester.
Arteta has been nursing a thigh complaint and also has not played since the Leicester win on September 26.
But manager Arsene Wenger said: "Koscielny has a slight chance to be back on Saturday. He has a definite test on Thursday.
"Arteta and Flamini are back in full training. We need to see how they are and how confident they are, but we can't rule it out."
Alexis Sanchez had been struggling with a groin complaint but he scored three times in Chile's wins over Brazil and Peru over the weekend - taking his tally up to nine goals in five games for club and country.
Wenger said: "From the internationals we only have positive news. We are still waiting for Joel Campbell, Alexis Sanchez and David Ospina to return, but they all texted back to say they are OK, so we just have to see if they were objective in their assessment."
