Absolutely.
I do believe the club have a plan, which is essentially spearheaded by the likes of Lange and, hopefully, Paratici. They've focussed on young talent integration so we have a solid, talented core in place for the next 5-10 years with a certain style of Football that they want to play. I believe that was why Postecoglou was brought in in the first place, as his was the brand of exciting, attack minded Football that the club wanted and we craved. For a number of reasons it hasn't worked out, but I still think that is the philosophy that the club will continue to pursue.
Frank does have that in his locker, so I can see the appeal, but I do have reservations on whether he can translate that to a higher level with a great deal more pressure to succeed. As I said, there's a World of difference between matching the expectations of a club like Brentford, and matching ours. Add in the additional pressure of taking over from the man who's just won our first major trophy in 17 years, and he could end up floundering.
Conversely, he could smash it out of the park, but whatever way you look at it, it's a rather large gamble.
Personally, I think he'd at least stabilise us in the short term, it remains to be seen whether he has the chops to go up another level in the long term. If he stabilises us for a couple of seasons, I'd be happy to have him longer to build on that.
