It's not all about the money, but rather how we use our resources well. We can't compete with City, United, the Spanish clubs, PSG and Bayern but we are clearly at Juve level. They have reached 2 European finals and signed players turned into superstars while after 4 years we are still trying to clear out dross. We have a nett spend as much as Chelsea in recent years but they have won more than us. Others are simply smarter and have more ambitions when they spend.
Of course, it also helps to have a manager who knows what he is doing. Spurs and Liverpool have far lesser resources as compared to us, but have been doing better on the pitch with what they have.
