I think you’re seriously underestimating how slowly the season ticket waiting list moves. I’ve been a member for years and you can never get tickets for big games. I’ve paid thousands of pounds to see the games season ticket holders couldn’t be bothered to show up for. I live 2 miles from the ground, and I’ll never get in to see games against City or Liverpool because thousands of people from down south will always turn up for these games. They’ll sit on their season tickets like dragons until they die. The ground is full of old people with season tickets and tourists willing to stump up hundreds to see a single match. The club are not coming to those of us who have paid premium membership for the last couple of seasons and offering us season tickets because tourists are worth more than locals
A new stadium will greatly increase the income of the club in the long-term. It will more than pay for itself and making more room for local fans and those willing to pay a premium for an ‘experience’. The potential for United to secure their place at the very top indefinitely will be unlocked by a new ground. It has to happen.
