A late Mario Balotelli penalty gave Brendan Rodgers' side a slim advantage from the home leg, and they travel to Turkey in fine form after an excellent run of results.
Sunday's 2-0 Premier League win at Southampton was their sixth triumph in seven games in all competitions, and the men from Merseyside have lost just once in 18 since mid-December.
Although their challenge for a top-four finish and UEFA Champions League qualification appears reignited, victory in this tournament would also see Liverpool return to Europe's premier club competition, regardless of their final league placing.
After losing Luis Suarez to Barcelona in the off-season, Liverpool's campaign got off to a stuttering start, but midfielder Joe Allen believes they are now back on track.
"Sometimes [criticism] gets taken out of hand but I don't think it was unfair," he told the Liverpool Echo. "There was no hiding places and we were not delivering as players.
"There was no excuse from us. We knew there might be a difficult patch early in the season and that probably went on longer than we hoped and expected.
"At the same time we always knew we would come through it and I think that was the biggest sign we would be where we are at this stage."
"We've had significant losses in two critical matches," he said. "There are significant [players] missing ahead of the Liverpool second leg but we will do our best to overcome it.
"Losses can be compensated in the league, but this is impossible in Europe."
Mamadou Sakho's hip problem is also a cause for concern after he missed the trip to Southampton, while Lucas Leiva (groin) is doubtful and Lazar Markovic remains suspended.
