You talking about coming to Camp Nou? No one at the club would want to bring in either. Their styles don't match the club's ethos.
Klopp would most likely go to the Prem if he ever left Dortmund.
I hope Cholo doesn't leave Atleti anytime soon. He's helped build a very strong team.
But in general if I had to pick one being better than the other, have to pick Cholo but not just because Dortmund is at the bottom of the table right now.
