Oh yeah, agree with all that. I don't even have a logical reason as to why either, just one of those weird gut instinct things. If I was to try and put my finger on it (and im free-rolling here so im sorry if its rambley) it would simply be down to how unique I think Pep's coaching and belief in his system is. Plus his almost savant-like genius view of the game. I'm not really convinced Vinnie's had the same footballing education in terms of coaching or that he has that same commitment to a 'philosophy'. I've certainly never heard him passionately talk about the way he likes a game to be played anyway. He's never really talked a lot about tactics, coaching etc in general, hence why many were surprised he'd gone into coaching. Most thought he'd go into the wider business world - including fellow pros like Bellamy and Bernardo (I recall him saying he could go into politics), which would indicate that maybe even they didn't think he was set for a world of coaching.
Guardiola learned a lot from Cruyff's during his formative years and I think he developed a real hunger for that side of things. I think it literally consumed his life and it's what he was born to do. I don't feel Vinnie's the same and I'm not sure he could get us playing in the same Pep way as I'm not really sure he's been exposed to that style for long enough. He's won in other ways and in different systems and as a result I don't think he's particularly passionate about the way Guardiola plays. Not that he dislikes it, just that I can't imagine it's the be all and end all for him, for understandable reasons. I may be wrong, but for Guardiola it was instilled in him from a young, young age. Not to say that Vinnie can't do it, but it just feels like what Guardiola does stems from a life-long belief in a certain way, that he won't ever budge from. I feel Vinnie's style, whatever it is, won't be what Pep's is cos I think that comes from the individual himself.
Conversely, I think Vinnie will try and go for a Guardiola style, but find it doesn't always click and not be able to put his finger on it. And the answer will be cos he's simply not Pep. I think this is what he may find difficult. As a result I think he may actually find a different way, and then it could possibly be that that's not what Txiki and co want.
All of this could be bollocks of course...just a heavily baseless theory :)
