Denilson ruled out but Walcott, Song and Diaby all set to return for Saturday's meeting while Van Persie, Bendtner and Ramsey will undergo fitness tests on FridayArsenal have received a major boost in their challenge for the Premier League title as a host of key first team players are due to return to action against Blackburn Rovers on Saturday.
Captain Cesc Fabregas is available again, while England winger Theo Walcott, Alex Song, and Abou Diaby are all in contention.
Gunners boss Arsene Wenger also confirmed Robin van Persie could feature despite picking up a knock against Hungary on international duty during midweek.
"Fabregas, Song, Walcott and Diaby will all be available," Wenger told reporters at a press conference on Thursday.
"I have not decided if they will start the game yet but they will all be available.
"Van Persie has a good chance too. He has a final assessment tomorrow but we believe he will be fit. It is a bruised knee.
"Nicklas Bendtner is in the same situation. He will have a test tomorrow on his ankle and we'll see.
"In fact, we have a few players with tests tomorrow — Ramsey with his groin, Bendtner with his ankle, Van Persie with his knee.
"I will make a decision after training in the morning.
"We just have Denilson out. It is short-term. We have one or two players with question marks but all the other players will be available."
Arsenal currently sit five points adrift of league leaders Manchester United, but have a game in hand on their title rivals.
