A lot of Tottenham's early-season issues stemmed from some basic errors. Both basic errors from players on the pitch - and common-sense decisions boss Pochettino didn't seem to be making.
Starting the campaign by naming Younes Kaboul as his captain was the worst possible foot to get off to at White Hart Lane. The Frenchman was performing poorly, losing the ball too easily and failing to offer any real leadership at the back.
To Pochettino's credit, however, he realised where his defence had been going wrong - and promoted summer signing Federico Fazio above the skipper. Tottenham haven't become a good side overnight simply because Kaboul has been dropped, of course, but it has brought about a vital defensive change.
White Hart Kane
Just like with Kaboul, Pochettino's decision to put his faith in Harry Kane was more common sense than anything. The 21-year-old was on fire in the Europa League and is now the in-form striker of the Premier League.
But the Argentine could have continued to keep Kane out of the picture, of course. He could even have loaned him out once again at the start of the season. Pochettino took his time with the young forward - and possibly too long - but has now got the very best out of the Spurs man, for whom the sky looks the limit.
Putting faith in Mason
Very similarly to how Pochettino got behind Fazio and Kane, his decision to stick with Ryan Mason in midfield has been inspired.
Not only has the 23-year-old proved vital to the Tottenham boss's tactical system, his inclusion in the side has fired a warning to Mousa Dembele and co, who are now fighting for their place much harder than previously.
At this moment in time, of course, there are a number of other Pochettino calls Spurs fans can look to with glee, while his overall approach - both in the dugout and on the training pitch - seem to be bringing much reward at White Hart Lane.
There are still aspects of his management that can be scrutinised, while Tottenham have a lot of room for improvement nevertheless. But, when your side is beating the Premier League leaders with ease, there's obviously plenty you're doing right.
