I think this is where people get me all wrong. I absolutely love what Son and Kane bring to the team. They may not do everything perfectly, but the things they do well are a joy to watch.
When I say he's a limited player, it doesn't mean he still isn't one of the very best players in the world. I said as much in my original post over a month ago now, but people saw the phrase "limited" and completely blew a fuse and there was no reasoning after that.
It just means that there are tactical problems he can't solve, same as problems Kane can't solve, owing to his lack of agility and pace. Mourinho is using them exactly how they should be used, but when that doesn't work we need a different solution. So I suggested that we either get a ball playing winger in the mould of Pedro Neto, Hazard, Mane etc to complement Son and Kane or Son learns to develop that side of his game.
Also there are different levels of "limited" right? The only thing Kane doesn't have is elite level pace/agility, so you might call him "limited", but otherwise he has no weakness. Kane is physically quite big/strong and can use that in holdup play and headers, he's probably the top 3 passer in the league, Kane is also a rock solid penalty taker. These are not strong areas for Son. Though Son is clearly better at taking set pieces.
I get the delusion aspect of it too, I get quite upset when England fans shit all over Winks and Dier whenever a teamsheet gets released with their names on it. Believe me, I understand.
Lloris is also quite limited. He only plays in goal.
