Not in any way, shape or form is that even remotely an indicator as to the future aspirations of the football clubs in question. Pure lunacy to suggest otherwise.
Spurs were on an upward spiral around the period of SAF's retirement (although they have leveled out the last couple of seasons) whilst United had entered a state of transition that would last half a decade or more. When you consider United's financial strength and brand, it is only logical to expect them to buy themselves out of transition and eventually a league title. Spurs had their chance during the Leicester anomoly and failed to capitalise. They are unlikely to find a better chance any time soon, not when you consider the financial strentgh of the teams that oppose them (those mentioned above).
