FC Dnipro Dnipropetovsk and FC København played out a goalless stalemate in Ukraine, leaving everything to play for in the return fixture.
Dnipro showed the greater ambition throughout the 90 minutes but failed to carve out any clear-cut chances against a well-organised København defence. Dnipro captain Yevhen Konoplyanka provided the central threat, registering six attempts on goal, but both goalkeepers ultimately registered clean sheets.
The Ukrainian runners-up enjoyed their best spell in the first half with Konoplyanka threatening from dead-ball situations and finding pockets of space in which he could turn and attack. The best chance of the game fell to Konoplyanka on the brink of half-time but the midfielder could not find the target.
The early exchanges of the second half provided little opportunity for goals and it was not until the game opened up in the last 15 minutes that Stephan Andersen in the København goal was called into action. The Danish club maintained good defensive discipline, restricting their hosts to half-chances.
The teams meet again for the decider in Copenhagen on 6 August.
