I agree with your point about Pep. The difference is that Pep won the treble at Barcelona in his first season in 2008-2009, and then 2 more league titles and another Champions league before leaving 3 years later. Get's you a longer leash for what you want to build, than ETH who has been successful in the Eredivisie and had some decent CL sucess.
I want ETH to stay and be successful but I worry that he will not make it because frankly, the results are not there yet and I don't know when they will get better. As another poster (sorry I couldn't find the post) said, it screams like the whole Frank de Boer saga at Crystal Palace a few years ago.
Reason why I never viewed ETH like FdB is because ETH was far more impressive in the Eredivisie, and in the CL.
Here is the stat I looked up a while back. Goals per game of all the best scoring Dutch sides of the past 12 years ranked.
1.
ETH 19' = 3.5 gpg
2. Jol 10' = 3.12 gpg
3. Advocaat 13' = 3.03 gpg
4.
ETH 21' = 3 gpg
5.
ETH 22' = 2.96 gpg
6. MVB 19' = 2.88 gpg
7. de Boer 12' = 2.74 gpg
8.
ETH 20' = 2.72 gpg
9. Cocu 15'= 2.71 gpg
10. Keizer, ETH* 18' = 2.62 gpg (* ETH only had 2.19 gpg after he took over).
11. Cocu 16' = 2.59 gpg
12. Cocu 18' = 2.56 gpg
13. Rutten, Cocu 12' = 2.56 gpg
14. Schmidt 22' = 2.54 gpg
15. Bronckhorst 17' = 2.53 gpg
16. Adriaanse, Mcclaren 12' = 2.41 gpg
17. Rutten 11' = 2.32 gpg
Notice the goals de Boer (7th place) put up against ETH's Ajax sides. And he was there for like 6 years yet only put up 1 high goal scoring season. ETH's brand of football is much more attacking, and I feel like there should be more belief in his tactics to translate into success.
