Tickets for the game that has been billed as the biggest in Irish club football history have gone on sale this morning.
Dundalk take on Polish champions Legia Warsaw in the Aviva Stadium on Wednesday August 17 at 19.45 in the first leg of the UCL play-off, before travelling to Poland the following week.
Tickets for the game start at €10 for adults and €5 for children and are available from ticketmaster.ie and the club ticket office.
Legia Warsaw have considerable European pedigree reaching the group stages of the Europa League for the past two seasons. While in 2012-13, they were unceremoniously dumped out of qualification for the Champions League after fielding an ineligible player in their tie with Celtic.
Victory for the Irish champions would mark a momentous achievement for League of Ireland football, with no domestic teams having qualified for the group stages of the Champions League since its rebranding in 1992.
