Seems to be members only for this match according to the description:
General Admission On Sale Dates:

Adult and Junior Members - Online and Over the Phone from 9 September 9:30am - If you're not already a member and want to buy in this sales window, CLICK HERE to purchase an AVFC Membership
But when I (I am a member) try to buy two tickets, it tells me:
The quantity of tickets owned by Walnuts, Paulie exceeds limitations.
To resolve, click "Assign Owners" and assign some of the tickets to other owners.
Too many tickets per event Aston Villa v Maccabi Tel-Aviv 06/11/2025 20:00: Please reduce the quantity to 1 or less.
Sales to this event are limited to 1 tickets per event per history per item owner.
Which suggests you just need a booking history. Which my brother doesn't have, and he's not a member either, so no tickets for us.
It's not the end of the world, I'll watch on the telly, but really, we do seem to make it hard to buy tickets. Even for league matches, I hardly bother trying these days because there will be plenty of individual tickets available dotted around, but just buying two tickets together is a ball ache.
I'm genuinely more likely to buy a season ticket in a bigger ground than I am a few one-off tickets because of stuff like this.
