How is this different from saying that "one of the dangers with a good manager is that the next guy will find it harder to take over"?
Pochettino's qualities in these areas is a benefit to us as a club. Hopefully he will stay with us for a long time, but if he doesn't I would rather have that benefit now than not have it.
The Southampton exodus would probably have happened regardless. Even I don't think Pochettino is THAT good... Could he have kept Shaw happy at Southampton when United came in for him? I don't see it.
Also worth noting that Pochettino left Southampton after they got rid of his mate Cortese after Pochettino had said he would leave too if they got rid of Cortese. But he stayed for the rest of the season at least. I might be overly optimistic about this stuff, but I think Pochettino is really enjoying life at Spurs now, enjoying his relationship with Levy and enjoying being at an ambitious club that he can help improve. Not sure his working relationship at most of the bigger clubs would be as good and I think he knows it. Fingers crossed...
Simple: player loyalty. Some of the best managers (I'm thinking of Pep here, but there are others) create brilliant teams that win trophies galore, but at the end of the day, when they leave, the players themselves don't all yearn to go with them: they understand that they're playing for the club, not the coach, who just happened to be a very good one appointed by the club. Look at Dortmund post-Klopp, as one illustrative example: he took that club from mid-table obscurity to multiple Bundesliga titles over the course of seven years, but the players immediately knuckled down when Tuchel came in last June (seamlessly adopting Tuchel's somewhat different style), and none of them have made noises about wanting to follow Klopp to Liverpool despite his evident success as a manager and his development of those same players.
There is such a thing as players being
too loyal to a coach over the club that pays their wages. It's one of the dangers that comes with appointing a charismatic manager like Poch who likes bringing through youth players and turning mediocre footballers into great ones: those players end up owing their careers to him in many cases, and it creates some tension when the manager (in this case, Poch) ups sticks to go to a club like United and then returns to tempt some of our players into joining him.
It's happened before, at S'oton: Rodriguez and Schneiderlin specifically wanted transfers to us because of their desire to play under Poch again to a considerable extent, judging by the news at the time (aside from our obvious appeal, of course), and there's obviously a danger of that happening here as well if Poch goes to a larger club that can then tempt our lads with higher wages and continued development under the coach that gave them their chance.
Also worth noting that Pochettino left Southampton after they got rid of his mate Cortese after Pochettino had said he would leave too if they got rid of Cortese. But he stayed for the rest of the season at least. I might be overly optimistic about this stuff, but I think Pochettino is really enjoying life at Spurs now, enjoying his relationship with Levy and enjoying being at an ambitious club that he can help improve. Not sure his working relationship at most of the bigger clubs would be as good and I think he knows it. Fingers crossed...
It's fine to be overly optimistic as a fan, but it's a terrible, terrible way to run a club. I do hope Levy's made plans for the possibility (and eventual certainty) of Poch leaving, and has tried his best to impress on our lads that, come what may, they're playing for Tottenham Hotspur, not Mauricio Pochettino. We've got a happy little situation here, with a good manager (and a good man, by all accounts) overseeing a good bunch of lads during an exciting time for the club, but that doesn't mean we can lose ourselves in the happiness of the moment and ignore the ramifications of it falling apart if that manager does leave.
