People saying he needs to go elsewere to get experience before we consider him as koemans succesor.
Guardiola had 1 season as Barca B manager before he took the big job there.
Now i am not comparing the 2 at all but it shows, experience isnt necesarily the most important thing.
Sometimes that experience can lead you to more cautiousness, take less risks, go stale etc. (look at moyes).
We all know RonKo is unlikely to be here past his 3 year contract, so i would put the wheels in motion for him to succeed him
..I presume he inherited a decent Barcelona team.
