The biggest insult you can pay Tottenham is that they are many neutrals' choice for the least objectionable member of the Premier League's Big Six, primarily because they haven't won a major trophy since 2008 (and even that was just the League Cup).
By rival fans, Spurs are often ridiculed for their tendency to fall at the final hurdle, but it's not really entirely fair. If you go by wage budget, the club regularly punch above their weight, finishing 3rd this season, for example, despite spending considerably less than London rivals Arsenal and Chelsea.
Of course, moral victories of this kind won't be remembered in 50 (or even 10) years' time. We'll simply refer to the history books, see that Man City won the title at a canter and Mauricio Pochetttino's side were 23 points off the pace, and conclude that the Argentine was a managerial failure.
If they are to escape this fate, Spurs need to get out of the habit of viewing any transfer window in which they manage to keep hold of Harry Kane and Dele Alli as a success. Instead, it's players walking into White Hart Lane that they ought to prioritise.
