I always feel like Frank has a serious attention to detail in his work. He is sort of a system manager but will happily switch things around for any game to make sure he gets the result. It doesn't always work but that is probably more to do with the resources at his disposal.
I've always felt under Ange we've had a decent philosophy but we've really lacked the attention to detail required to make it work. There's definitely been no "soup to nuts" approach with Ange and his coaches. We often talk about these flaws in the way we see players behave on the pitch.
Now that we've for the big monkey off our backs in winning a trophy, I can definitely see why we'd look at a manager who has very similar traits to Pep, Klopp, Slott, Arteta etc. Some question marks about Frank's philosophy but then I'm sure Pool fans would have said that about Klopp when comparing him to Pep who has played the more attractive brand of football over the years.
Of course, it's not just about Frank. It's about bringing in the 4 or 5 guys that work with him. We would need the entire package if we're making this bold move.
