I would love Klopp on Barca bench. Second choice Sampaoli.
I dont see any other good long term option, maybe Valverde, but thats it.
Lets not waste Messi's years and bring in top manager. Lets see the coaches he had (Rijkaard, Guardiola, Tito, Tata, Enrique). Its about time he gets a good coach. If you look at it most of them were noobs, Pep turned out great, but others not so good. And knowing our board we will go for someone like Koeman.. smh
