Let's go back to the average UK wage of £31k for the UK.6% doesn't sound a lot but taking your figures you have already apparently offered 24% of your yearly revenue. That is my point, the starting point to here is already fu****g huge. You can't remove the £120m or 24% of revenue from the context here and say its only another 6%, its 6% on top of an already astronomical figure. I'm 100% certain Spurs aren't moving from that figure, they may move slightly in terms of included easily met add ons but the headline figure will remain unchanged.
You want to buy a car. You're offering £7500 currently. The seller wants £9300. That is not an astronomical or insurmountable gap.
