Midfielder Francis Coquelin was also substituted in the final stages of Tuesday's match with a knock but Wenger expects the 26-year-old to be fit to face their fellow top four contenders.
"He came back and I think it's a positive game, he is 20 years old and what he showed in a game of that stature is very good".
On playing against Salah, Maitland-Niles told Arsenal's official website: "I think I did alright".
Liverpool appeared to be in control of the game as they stormed into a first half lead with goals from Philippe Coutinho and Mohamed Salah, but Arsenal scored three goals in five insane second half minutes to storm back into the game. You have to go for it, that's what you want for a player.
But rather than rue the alarmingly creaky defensive play from both teams, Gunners boss Wenger insisted he was pleased to have been part of such a memorable occasion.
"I guess it's just how to deal with those powerful, attacking players that love to score goals and run past you; It's a learning curve to play against them and use their weaknesses against them", Maitland-Niles added.
"Overall we played too deep, too far from each other, but we were much more compact in the second half and after that we are even frustrated in the end because we were 3-2 up and could have won the game".
