I don't think any standing areas are allowed for the qualifiers. Had a look on UEFA's champions league regs and it says;
Unless stipulated otherwise in these regulations, matches in the competition must
be played in a stadium which meets the structural criteria of the following
categories as defined in the UEFA Stadium Infrastructure Regulations:
a. category 2 for the first and second qualifying rounds;
b. category 3 for the third qualifying round;
c. category 4 from the play-offs to the semi-finals
Did a search for the Infrastructure regs ans for Category 4 it says;
Section 2: Spectator-related areas
Article 75 - Stands and spectator facilities
Any standing accommodation as defined in Article 3(1) (i) is prohibited.
For some reason, I can't copy and paste a link in here sorry but it let me copy and paste the text..
Ta,
Just had a look at something else and standing is only allowed in category 1, so no standing allowed in any of the qualifiers.
