The Lilywhites trail 2-0 from the first leg
Dundalk FC make their way to Warsaw for tonight's game with Polish champions Legia Warsaw, knowing they'll need to score at least two goals to progress to the group stages of the Champions League.
The Poles won the first leg 2-0 with a penalty from Nemanja Nikolic, followed by a late goal by Aleksandar Prijovic to double Legia's lead.
Stephen Kenny's men will hope they can repeat their heroics of last season, when they overturned a one goal deficit to win away at Hajduk Split in last year's Europa League.
However, the County Louth side are at least assured of a place in this years Europa League.
Kick of at at 7:45pm.
