May help some I guess,
Wembley have some accesible seats left for people in wheelchairs and can bring 1/2 people with them.
Managed to get 3 tickets for myself and my daughters on 16th August.
My youngest gets higher rate DLA and you need proof and obviously the wheelchair user has to be there too.
They had some limited available for other dates too, even the June ones ,
The access line number is 0800 093 0824
I don’t know if anfield has any as I wasn’t taking the girls to that shithole ;)
