The more I read, the more I think I would prefer Klopp. As much as Carlo impresses me, he seems to rely more on brining in established players. Whilst LFC are reasonably competitive financially I'm not sure we could sustain what could prove a very costly approach. On the other hand we seem to have wasted quite a bit of money on experimenting with players' potential.
I'd say Klopp just shades it though, because he just comes across as more capable of utilising our setup and maximising its potential.
