Hello! Tickets for England's Liverpool home team are hard to get, especially on match days. Generally speaking, tickets for home games are distributed through lottery, not through official channels. Therefore, you need to register as a club member to be eligible for the lucky draw. If you are not a registered member, you may need to spend more money on tickets.
If you want to buy a ticket, I suggest you log on to the livefootballticket website. This website claims that if the tickets are not found 24 hours before the game, it will directly compensate 150% of the ticket price.
