Wenger is quite similar to Klopp in that they both have similar traits when it comes to building teams/squads, both seem to favour loading their teams with attacking midfielders/wingers.
Klopp has loaded the Liverpool team with them and spent millions doing so when he has major issues with Keepers, Central Defence and to a lesser extent Central Midfield.
Klopp was brilliant at Dortmund in the early years but his stock has not risen for a while now. I'd have him over Wenger as I think he's a bit more adaptable but he's not elite.
