Levski Sofia and AEK Athens produced a tight, goalless first leg in their UEFA Champions League play-off tie, with neither side able to find the breakthrough at the Stadion Vasil Levski.

The two clubs go into the second leg with everything still to play for, the tie perfectly poised after 90 minutes of football yielded no goals and no clear winner on the night.

The result leaves both teams with a genuine chance of advancing, setting up what promises to be a decisive second encounter.
