Youre old fashioned!
Seriously, I can see your point but from where we are now it is hard to see what the long term plan should be. Pochettino? If the club went that way I would support it but it does seem possibly a bit early for him, he could do with staying at Spurs to see if he can actually deliver on the promise he is showing. If Mourinho comes and gives us 2 or 3 seasons or whatever it buys us time, which, if Woodward was prudent, he would use to think carefully about what our next step should be, and start preparing the groundwork. I dont think people are saying Mourinho will turn out to be the long term solution and will be with us for decades - it would be nice if he did, but that isnt the point. It is that there are no strong candidates available who will clearly stay at the club for that kind of timeframe - in fact, there may never be.
I did used to think like you - I think a lot of us did to some extent because it was how SAF thought and it rubbed off on all of us. But I think we need to start flipping it around and think of longevity as the product of success, not success the product of longevity. Meaning, you cant appoint someone and assume that if you give them 10+ years that everything will work out, you need to appoint someone who will deliver the goods, and if they do that, with a bit of luck, we may keep them for a long time because there arent too many jobs around that would entice a good manager who was successful away.
I thought Mourinho would settle at Chelsea for the long term as it happens, I said so on here quite a few times and I was proved wrong, circumstances didnt allow it and the same may well happen if he came here. But I dont think he actually wants to play the field anymore, where else would he want to go? He has done Spain and Italy, he said he prefers England. He has tarvelled and experienced new things, he may want to settle down, I think he would have at Chelsea if he could have. Obviously he may end up falling out with the players or Woodward or the medical staff or whatever, if he does we deal with it, and like I said, Woodward would need to plan for that eventuality.
As a few others have said above the essence of the issue is that there is no candidate around who has the requisite experience who we can guarantee will stick around for a long time. We have to take a risk one way or the other, either by appointing someone with less than the ideal amount of experience, or appointing someone with a history of falling out with people he works with. There is no one candidate I am supporting in this at the exclusion of all others, Pochettino and Mourinho both look good candidates to be fair, but Mourinho looks more qualified to get us back to where we need to be in the short term so I am gravitating towards going that way and hoping we are in a stronger position by the time he leaves, in which case hopefully another good candidate will be available at that time (again, Woodward's biggest job is to facilitate that transition.)
