Monaco trio Yannick Ferreira Carrasco, Jeremy Toulalan and Geoffrey Kondogbia have returned to training with Monaco and are all in contention to face Arsenal on 17 March.
The Gunners are on the brink of elimination from the Champions League following their dismal 3-1 home defeat to the Ligue 1 side in the first leg of their last-16 clash on 25 February.
Veteran midfielder Toulalan was suspended for his side's victory at the Emirates Stadium but Kondogbia, 22, and Carrasco, 21, were integral to the result, both getting on the scoresheet.
The trio missed Monaco's 3-0 win over Bastia on 12 March with respective injuries but trained with the first team as normal on 16 March. All three are now expected to feature against manager Arsene Wenger's side, L'Equipe report.
Monaco have received a further boost in the return of Ricardo Carvalho to their back line. The former Chelsea defender missed his side's first leg win in north London but the 36-year-old returned for Bastia league victory where he completed 90 minutes for manager Leonardo Jardim's side.
While his side hold the advantage, Carvalho has warned Arsenal are more than capable of turning the tables when they visit the Stade Louis II.
"I don't know [if Arsenal underestimated Monaco]. I don't think so," the former Chelsea centre-back told Perform. "Sometimes that happens in football. Of course, for most people it was a surprise.
"Arsenal are a great team, but sometimes in football, it's true that it can happen. So it can happen with us at home, so we have to be ready to play well, because in football you can have that kind of surprise."
Meanwhile, Arsenal will be without Alex Oxlade-Chamberlain for their visit to Monaco. The 21-year-old netted a wonderful effort that briefly sparked hopes of an Arsenal comeback in the first leg but is facing a month out of action with a hamstring injury.
