The eight-times champions of Poland take on the 12-times champions of Sweden for a place in a major European quarter-final.
Last summer, Djurgårdens IF qualified for a UEFA group stage for the very first time by beating Rijeka, Sepsi OSK Sfântu Gheorghe and then APOEL.
Once there, they could easily have been mistaken for seasoned-veteran, accumulating 16 points and topping their section with ease.
So, Djurgården are on the cusp of reaching the last eight of a UEFA competition for the first time since 1960.
The biggest challenge facing Kim Bergstrand and Thomas Lagerlöf’s team will be a lack of match-fitness.
The new Allsvenskan season doesn’t kick off until 1 April, with the Blue Stripes beating minnows Landskrona, Örebro and Brommapojkarna in recent Svenska Cupen fixtures.
This will be a substantially tougher task, so can Djurgården rediscover their pre-World Cup form?
Lech Poznań, in contrast, have already overcome a Nordic club in the knockouts, ousting Bodø/Glimt last month.
The only goal of the tie was scored by a Sweden international, namely Mikael Ishak, coming in the second leg in Poland.
Having finished above Hapoel Be’er Sheva and Austria Wien in the group phase, the Railwaymen are competing in the knockout stages for the first time in 12 years.
Now, John van den Brom is dreaming of leading the Ekstraklasa champions into a European quarter-final for the first time ever.
Will Lech make home advantage count at Stadion Poznań?
