I didn't mean any particular club should sell its allocation more that the game itself should have enough fans regardless of who they support who want to go and watch the grand final selling out the stadium.

I think that you are missing the point.
I'm not sure what the allocation of tickets is for each finalist but, assuming that it's 15,000 ??, then Catalan are very unlikely to sell those before the final.
At what point should they be put on general sale and will there be time or the inclination for other fans to buy them.

There really should be something in place in either of the finalists cant sell their allocation, assuming of course that the remainder of the tickets have already been sold ?

We go every year and will look forward to Saturday. I’ve missed one through choice since 1998 (I think it was 2009 when Lee Smith played a blinder) and the other lads haven’t missed a single one until Covid took their record last year. The RFL will surely work on a plan now to close a lot of the top tier areas and get that bottom level full. It is a great final for the neutral but it’ll do well to break 50,000 I reckon. As long as they manipulate the areas people can sit in that will look ok on tv. The fact Catalans are in the final probably can’t be measured but I certainly don’t see it as a negative.

Looking on the seating plan they currently seem to be selling seats every other row to make it look more full and the top tiers in some stands currently not on sale.

Four foot snake, For ages I've seen comments about wanting to see different teams in a Grand Final, we get one and it prompts posts about the crowd being down.

I don’t think they’ve given cats an allocation? Just a link on their website and direction to buy in that end...all Catalan end are in general sale and top tier is shut (presumably to open if they sell out the bottom tier). Best way of doing it imo as they’ll not be more than 2k from the south of France simply because that’s probably the maximum that can get here, unless thousands are willing to do a 15h car journey and covid tests like Tomkins did etc. So let the neutrals take them up

Sales don’t look great atm but you’d imagine a couple of thousand catalans and hopefully 10k neutrals will fill up the Catalan end and cheer them on.
Recon we’ll be looking at a crowd of 10k short...about 58-60k with top tier behind the Catalan goal shut. If that’s the case it’ll look fine as long as they get the tv angles right...having been to most recent GFs Saints and Wire have both only half filled the top tiers behind the goals at times and you hardly notice

...but what doesn’t make sense is that they had a promo on with Man U last week, with 20% off tickets with code MANU20.
Yet the code isn’t now working.

Surely you want to encourage 5-10k United fans with discounted tickets...I think that happened for Salford the other year and prob needed again

The point is that there should be a plan for selling the "spare" tickets quickly.
I'm pleased that Catalan have made the final and they certainly deserve it.

Should be great final but, Saints getting done a few weeks ago by Catalan in the last 5 minutes should give them some extra motivation (although they shouldn't need it) and I cant see anything other than a Saints win.
