Arsenal could welcome Eduardo back from injury for Sunday's clash at West Ham, while Tomas Rosicky and Nicklas Bendtner are rated 50-50.
The trio missed Tuesday's draw with AZ Alkmaar in the UEFA Champions League through injury, but they are making progress with their fitness.
Eduardo has recovered from a thigh problem, while Rosicky has a knee complaint and Bendtner is aiming to shake off a groin injury.
Theo Walcott is definitely missing after sustaining a knee injury in last weekend's win over Birmingham.
"Rosicky (knee) and Bendtner (groin) are 50-50 but Eduardo (thigh) should be back," Gunners boss Arsene Wenger told the club's official website. "I would say only Walcott is definitely out."
Samir Nasri and Lukasz Fabianski both made their comebacks in midweek in the reserves, but Wenger admits he will not take any risks with the pair.
"It is possible [they will be included]," said Wenger. "But it depends on our needs. Ideally Nasri will need the game against Liverpool to be completely part of the squad again. So it depends on the urgency."
Wenger also revealed long-term absentees Denilson and Johan Djourou remain on the sidelines for the foreseeable future.
Denilson has been out of action for over a month with a back injury, while Djourou underwent knee surgery in September.
Swiss defender Djourou is not expected to be back until March, but Denilson could return next month.
"Denilson (back) should be available in four weeks and Johan Djourou (knee) will be March," he added.
