Yes, backwards. You aren't winning the title this season, just like you didn't in 2015/16, and just like you didn't in 2016/17. You aren't winning it next season, or the season after that either. You've had your day in the sun, picked up your "ran Chelsea close" cup, and now you're busy fecking around with a stadium that should be finished but isn't. Best start, blah, blah, still 6 points off top.
The only way for Spurs to go is backwards. You've a stadium to pay for, and that's going to seriously squeeze the budget for future transfer windows. Arsenal are resurgent. Chelsea are resurgent. Liverpool seem to finally be getting their shit together as a top team, and City are City. Should United get their shit together, you'll have us to contend with too. You aren't overtaking the teams above you, and are well in the sights of the teams below you.
At a certain point, the amount of money becomes somewhat redundant. We're more than rich enough to combat City's wealth. Spurs have a better squad at the moment, but they've a stadium to pay for, and have already had one summer with zero investment.
The expectations are higher at United, but I'd like to think whoever we bring in now is being brought in because they have a vision to take the club forward, and will be given sufficient time to do that, even if that means switching the focus away from silverware for a few seasons, and back onto playing an attractive style of football that pleases the fans and gets us back competing with the top clubs. If we bring him in and tell him he's to deliver a league title in three years then yeah, obviously that's shit, but I don't think we will do that.
