For the ManU prem match you need albion+ and 50 points to have a decent chance of getting tickets, although I don't know if they got down to albion+ without 50 points
there are still loads of tickets, if you only want one you have a pretty good chance - probably be able to get a couple together I recon, don't give up!
I don't think so - should have a better idea after the first release to albion+ members - there are still loads of tickets so don't panic, just be prepared when it is your go
