No, but just assuming he can adapt is also wishful thinking. With the squad he has, constantly being nearly men isn't good enough, especially for a manager that many on here consider the second coming. Fact of the matter is, if he can't win a title there with a squad that imo challenges City for the best in the league (first eleven anyway), then he isn't going to be able to muster one up here with the current state of our squad.
Squad depth is an issue, but I doubt he wasn't given money to spend, that's on him. He's got players like Son, Lamela, Sissoko, Llorente, Dembele - who can play as replacements for Alli and Eriksen, his insistence to play them is down to himself.
Are you not contradicting yourself within these two paragraphs? In terms of 1st xi, I don't think there's any disputing that Spurs are one of the best in the league - if it were the 90's and 1st xi's plus a mish-mash on the bench was status quo like it used to be, there's no reason why they shouldn't challenge for the title, as you say, but in the here and now, in the age of mega squads and player arms races, it's a very different story.
If they were only contesting on the domestic front, I think they would have little to say they shouldn't be right up there, but when you add in the CL variable, all of that goes to pot and the squad becomes a vital component in keeping everyone fresh whilst still being able to accrue points.
Apart from Son, who is of the level required to be a game-changing/contributing squaddie, you've listed: Lamela - who has only just come back from injury, and needs to be eased back into competitive football; Sissoko, who is a laughing stock*; Llorente, who would be a third of fourth choice back-up at a bigger club; and Dembele, who is an injured crock these days.
That is not a grouping that is going to do anything of note for Spurs in the absence of their top players.
*Sissoko, you can point out that they shouldn't have bought him in the first place, but the point here is that at bigger clubs, a punt like him is just put to pasture and others come in to fulfil the role until a replacement is purchased.
You can argue that those players are stepdowns from the Alli's and Eriksen's which fair enough is true, but our replacements for Martial and Rashford is Lingard. Our replacement for Mkhi is literally nobody as we don't have another proper number 10 in the side (Mata hasn't played there consistently since I can ever remember). Our replacement for Pogba is either a walking pace Carrick or Herrera who essentially just steps on the feet of our other best midfielder Matic.
Our replacement for Valencia is Darmian or another makeshift winger in Young.
Our workarounds are on a completely different level to Spurs'. We might say they are not 'MUQ' but they are more than capable of doing a job and it's better to have them than not. To have the likes of Mata and Mkhitaryan twiddling thumbs on the bench because they are not to our liking is a luxury - or privilege - afforded to the big clubs. That we don't even allow them to play themselves into form, because we can make do without them, is also testament to our options.
We have the choice to do what we do, whereas for the likes of Spurs, everything is pretty much backs to the wall with little to no margin for error in purchases or fielding.
They have a few very good options at fullbacks, Davinson is a very good centre-back even when Alderweireld is out, they have more than enough options in the centre of the pitch with Dembele, Sissoko, Wanyama, Winks etc. They have Son, Lamela etc. to replace Alli and Eriksen. The only place they don't have a proper replacement is Kane and that's a given considering he's probably the best striker in the World atm - even then they have a very good PL proven player in Llorente.
Covered above. In terms of their defensive unit as a squad - do you really think it's comparable to ours? We pretty much have 5 interchangeable CB's to choose between on any given matchday, and at that, we can select for specialist skills or drop whoever because they are out of form... can, or do, Spurs ever do that?
Our fullbacks are not to our liking because we're measuring ourselves against the best clubs in the world, which is the difference.
He's underperformed imo and all this talk of squad depth is just clutching at straws to try and defend the new shiny toy on the Caf. He's a very good manager and he's done wonders at Spurs to improve them the way he has, but not winning literally any proper silverware in his career is not good enough imo.
The squad element always becomes a factor once the CL is introduced - just as it was stated before a ball had been kicked that it would cause Chelsea bother as has proven to be the case.
To go for trophies, Spurs would have to prioritise, which would then be frowned upon. If he rested players in pursuit of the CL or FA Cup, there would be ridicule. If he rested players in the CL to focus on the league, there would be ridicule. I don't get the line of reasoning where he has to win trophies to prove himself if the above caveat is going to be ignored.
Whatever you think of him as a manager, to just throw out the factors that don't fit the narrative you want to have for him simply paints a non-objective picture.
All things should be considered equally and then thoughts formulated from there... if you want to be fair, of course.
