It’s been done at the expense of the club finances, the project should have been put on hold until it was 100% funded and focus put on the team not the other way round
That's not how any stadium over say 10,000 seats is built. We don't have the headroom to nestle away 50-100 million a year into the stadium funding pot and by the time we did we might find we need another 250 million as everything has gone up, by the time we have that extra it's gone up another 80 million and so on.
What your mixing up here is saying all debt is bad. If you take out loans and you use that for the transfer fees for Sigurdsson, Mina, Bolasie and Tosun then that is obviously very bad debt as it had no return and with playing staff that is always a risk. BM should take our matchday income from 12-15 million to around 45-60 million, as long as that extra services the debt you have a new stadium for nothing. It isn't money you were ever going to have at Goodison so you can't say I will divert that money you spent on BM into the team (see the bad debt thingy above).
Now if you can generate more money than it costs to repay the loan and plus what we earn at Goodison then that is extra you can spend on the team year on year to make improvements. This stadium gives opportunity to do so through corporate events, meeting spaces, concerts, much more chance of a larger stadium tours income and general sponsorship. That is the point of having a new stadium and yes there is pain as there is always a hump until it opens and starts to generate income, but it is more than worth it in the end.
