Greek champions Olympiacos will play either Zrinjski or Slovan Bratislava in the third qualifying round of the Champions League.

The Piraeus club failed to reach the group stage of last season's competition, suffering a surprising loss to Anorthosis Famagusta.

However, they made it all the way to the last 16 of the 2007/08 edition before losing to Chelsea.

Zrinjski, who are the Bosnian league winners, hold a 1-0 advantage over Slovan after the opening leg of their second qualifying round clash.

Czech title-holders Slavia Prague will take on either Finnish side Inter Turku or Sheriff Tiraspol of Moldova.

UEFA Cup holders Shakhtar Donetsk will enter Europe's elite club competition against Romanians Timisoara, with the Ukrainian side staging the opening leg.

Shakhtar beat Werder Bremen in last year's UEFA Cup final, the last time the event was played under that name before becoming the Europa League.

Panathinaikos take on regular Champions League participants Sparta Prague, while Sporting Lisbon, who won the Cup Winners Cup in 1964, meet FC Twente.

Former UEFA Cup champions Anderlecht will host Sivasspor in the opening leg of their third-round qualifier.

Dinamo Moscow make the trip to Scotland to take on Celtic at Parkhead.

Under UEFA's new seeding system for the tournament, clubs which do not qualify directly into the group stage have two ways of reaching the next phase.

One way is for teams progressing from the second qualifying round via the Champions Path. The other, known as the "Best placed Path" is for the remainder - for those participating in the ties to be played on July 28/29 and August 4/5.

The winners of the five best-placed path ties will then face one of Arsenal, Lyon, Stuttgart, Fiorentina and Atletico Madrid in the play-off round.
