If Klopp is available and fancied the job after a rest, the FA would be mad to turn him down.
Pep is simply the greatest manager this country has ever seen. No one comes close to him in my book. However if Pep wasn't around then it's almost certain Klopp would be right up there with the silverware.
His teams are decent enough to watch and he does get the best out of players. I agree with the others who say his tactics are probably easier than Peps, although there is the issue of whether they'd work after a long season.
Klopp has been there and done it and I'm certain he'd get us close to titles.
If not then Potter or Howe would be fine with me.
