I don't know mate but I've seen headlines trumpeting their tickets sales e.g. https://www.liverpoolecho.co.uk/spo...erton-season-tickets-record-renewals-18696860 I expect that they are in a minority who have season ticket offers.
Covid-19 will be done soon, I'm pretty sure. Cubs need to plan what they are going to do.
Even with reduced capacity selling season tickets at the moment does not guarantee you a seat unless on the season ticket they say you will get 19 games even if it takes 3 years for you to use it? That could be a way ahead I suppose?!
