Chelsea tickets

Have the upper tier tickets all sold out or not been put on sale yet. I assume the 3000 allocation includes both upper and lower as usual. Its just that at the moment they're only selling lower tier tickets on e ticketing

I bought one for the upper yesterday, so a good chance they’ve sold out, if not showing now

I got 2 for the upper tier yesterday. Only lower tier available today. Assuming upper tier is already sold out.

Thought I read somewhere that we were getting 1500 tickets first ( upper & lower ) then if they go we can get another 1500 ?
