It's odd that the same media outlets reporting these managers are resigning due to burnout are linking them with the high profile positions the other burned out managers will be leaving...If, for example, Xabi Alonso is burned out at Leverkusen, why on earth would he want to leap into managing Liverpool?
I have read Klopp's statement through and he explains his reasons pretty clearly. Last season was rough, and through herculean efforts he has managed to right the ship; the playing squad is in good shape, with plenty of players either just emerging or in the prime of their careers.
But when the time came to start planning the next cycle of training, signings, competitions, and whatnot, Klopp began to feel a little hesitation to leap back into it. He realized he didn't want to be used to lure in players or prepare training plans if he was beginning to think of an exit. Which precipitated his decision to call time now, while the next season is still well off and can be prepared for.
Whoever comes in next will NOT be getting a played-out squad at the end of its cycle, or an ownership group in turmoil, and they won't be coming in with no preseason. That is good stewardship, and I can't argue with his logic. If he's feeling like he might not have the energy for another cycle, this is the best time to act.
After watching Hendo's fall from grace it would be a nice change for Klopp to leave in a way that cements his positive legacy with the fans and the city.
Barcelona's ownership were (are) greedy and reckless, and they have made their bed; now they can sleep in it. I have zero sympathy for them. Messi is smart enough to keep his mouth shut most of the time and thus avoid trouble, but his people are grasping and acquisitive. He may be a decent fellow himself, I don't know, but his 'brand' is a financial juggernaut that helped bleed Barcelona white and is shilling for Saudi Arabia (though, cleverly, he is doing it without having to play in their silly league).
