The matches were held on 14 September (first leg) and 28 September 2006 (second leg).

4Due to the armed conflict in Israel, UEFA had ruled that European tournament matches could not be played in Israel until further notice. Maccabi Haifa's home leg on 14 September was moved to Nijmegen, Netherlands. On 15 September, UEFA lifted the ban, allowing future matches to be played in the Tel Aviv area. Hapoel Tel Aviv were able to play their home leg in Tel Aviv on 28 September.

5UEFA ordered Trabzonspor's home leg on 14 September to be played behind closed doors after objects were thrown at visiting fans and the fourth official, and a smoke bomb ignited in the stands, during their second qualifying round home leg against Cypriots APOEL. Trabzonspor appealed, and UEFA rejected the appeal on 13 September. Trabzonspor's penalty includes a second closed-doors game, a penalty which has been deferred for two years and will be removed if no further incidents occur.
