I hope you are correct.
It's not about 'fun' for me though, but it is about seeing hints of vision and determination, and things that might not work at the moment but that they work on and might improve a lot over time.
I think there is a window in the first weeks-months where a new leader can set standards - it is very tough to make BIG changes after that.
Him waving the players back in the last liga game for example, or his treatment of Luuk v Depay in the last games... Signs of almost cowardice to me, I don't see him making many daring decisions. Maybe some things like signing Alves could be seen as daring though (to me it looked very obvious)
There's a fine line between daring and naive. I actually think Xavi is proving a lot of people wrong by being cynical. There were a lot of worries about him coming in with a carbon Pep copy tactic.
But yeah, I also hope we can boot out the oldies ASAP and play a Xavi incused type of football. But I think it's easier said than done.
