Oh yeah I completely agree with that. This formation barely suits anyone in our squad.
Son is an inside forward who likes to run in behind, but Ange shunts him out on the wing.
Brennan likewise; inside forward on at Forest, dangerous on the counter; I know! Let's spend 50m on him and play him in a possession based system where he's spends the game on the touchline with no space to operate and is tasked with taking on fullbacks from a standing start (which he's crap at)! Great recruitment Spurs, great talent ID Ange.
(Also shame on those of you who spent the last few years shouting down criticism of Brennan just cos he scores the odd tap-in, when he's so obviously not at our level. Unsurprisingly it was plenty of those same names who are now the Ange-inners who evidently must watch the game with their brain disengaged. It was obvious to anyone with an iota of ball-knowledge from his Forest highlights Brennan was going to be a terrible fit in this system).
Kulu, another inside forward with talent, but Ange forces him out wide or in the #8 and he's not perfectly suited to either. Despite what people claim he still hasn't got the positioning right in midfield and we're often very open centrally when he plays there. He's best in a narrow-ish front three on the right, and another who suits counter attacking football best, hence why his best time here is still that first 6 months under Conte.
Our fullbacks are all natural wingbacks at heart. Yet Ange forces them to all play in this stupid inverted #10 role he "invented" (and nobody else uses - I wonder why) and they all look like fish out of water.
We don't have any natural single-pivot #6's. All of our DM options have drawbacks in the role. So we could do what Slot does—or Pep when he doesn't have Rodri, or Arteta, with his inverting—and play a double pivot? Nah let's force Bentancur/Bissouma into an ill-fitting role where they have too much work to do and are constantly exposed. Genius.
Ultimately, the great managers adapt their system to suit their players. Ferguson, Pep, Ancelotti - always changing their formations to get the best out of the players at hand.
Mediocre managers try to force ill-fitting players into a rigid system (Amorim, Conte). Sometimes they'll have success when all the stars align, but when it goes bad it goes really bad.
Bad managers have a shit system to begin with, are inflexible with it, and buy the wrong players for it.
Guess which one we've got.
