This is a very good point.
A faction of Spurs fans have this weird phenomenon where they vastly overrate our players based on a few good games they had at some point during their career here.
Kulusevski is a good example as you say. A good player but hugely limited in a lot of areas and doesn’t really suit the way the manager wants to play as a winger.
Bissouma is another one. A guy who has been absolutely bang average for a season and a half for us bar a few games at the start of this season, yet there are still folk banging on about him as “one of the best in the league.” Based on what??
You also regularly hear from the usual suspects “Pochettino should have done so much more with the team he had” a line that always baffles me, as I am at a loss as to what it’s based on. What had any of those players achieved in the game prior to him arriving at the club? And what did they achieve after he left when “guaranteed trophy” managers took over?
It’s just their suble little way of saying “it can’t be the owners fault we failed under Poch, he was provided with the players.” And the same nonsense will likely be spouted by the same crew if(when) Ange comes up short in a similar fashion.
Just mind boggling levels of revisionism, delusion and ignorance to constantly defend our ownership, and for what?
