For a caretaker he's a excellent choice. He did the same at RB Leipzig when Hassenhuttl resigned and he took the reigns for a full season before Leipzig were able to get their preferred target which was Nagelsmann. And in that season, Leipzig achieved the best defensive record in the league which Nagelsmann couldn't better and Leipzig scored a similar amount of goals as what Nagelsmann's teams produced.Possibly. That's why I asked. He's currently a sporting director in Russia. Hardly a glowing endorsement is it?
Hardly think the creator of the gengenpress is what we need with Ronaldo either. That won't work with Ronnie.
But having said that, he probably won't be available as Caretaker.
