The Gunners have performed well in their recent games and have won eight of their last nine matches in all competitions with the only defeat coming at the hands of arch rivals Tottenham. Much of their good form has been down to key men returning from injury which has given manager Arsene Wenger a wealth of options to choose from.
Whereas the Frenchman will certainly be in a dilemma as far as team selection is concerned, summer signing Danny Welbeck has termed it as a 'good headache' and has claimed that competition will get the best out of every player.
"There's a lot of attacking options which gives the manager a good headache to have," he told reporters.
"Once everyone's on the pitch we're going to give 100 per cent and give the best for the team.
"That's the most important thing - once you’re on the pitch you need to do your job properly. Whoever comes in will obviously do the same."
Despite of going into the match as favourites, the former Man United man has insisted that his side will not be taking their opponents on Wednesday lightly.
"We know that it’s going to be a tough tie for us, it's going to be played over two legs so we're not just going to be focused on this one," he explained.
"You know every single game means a lot and you have to try to get the best out of each match and get the win on the day.
"Going into the game we have prepared well, we have analysed their team and we are looking forward to it."
Monaco on the other hand have been inconsistent as of late and followed two losses with two consecutive wins. They were against Nice last time out in a league encounter which they won through a solitary goal from Bernardo Silva.
Former Tottenham man Dimitar Berbatov who now plays his trade at Monaco is aware of the task at hand on Wednesday, but he is hopeful his side can earn a positive result.
"It is nothing new to me. I know the games, I watch them on TV, Arsenal are playing very well," he said.
"They are a team who work a lot of passes, try to play the combinations, football the way it should be played. They play on the counter with quick players and very technical.
"Maybe this will be new for some of my team-mates, but I have explained to them that it will be difficult, so they need to do their homework, and our coach will prepare us for the game.
"Hopefully we can do what we came here to do."
