Olympiacos – Veria

Pep Guardiola's side will be expected to make light work of progressing to the second round when they travel to the Preussen-Stadion this weekend.
Preussen have won just one of their four games in the third tier so far this season, but will be relishing the opportunity to pit their wits against the Bundesliga champions in an eagerly-awaited first-round tie.
It would be no surprise to see Guardiola ring the changes from the 2-0 DFL-Supercup defeat to Dortmund on Wednesday for a clash that comes just five days before the Bavarian giants commence their Bundesliga campaign against Wolfsburg at the Allianz Arena.
Dortmund also face 3. Liga opponents in the form of Stuttgarter Kickers - setting out on their their quest to regain the trophy they won in 2012.
The Kickers have won their first two home matches in the league this season, but Jurgen Klopp's side will be a different proposition altogether at Waldau-Stadion.
Schalke face a trip to Dynamo Dresden, who are joint-top of the table after winning three of their first four 3. Liga games following their relegation last season, in one of four first-round fixtures to be played on Monday.
