OK let's think about this based on previous managers.
Redknapp:
Strengths - man management, experience, adept at keeping the media on his side.
Weaknesses - tactical knowledge, short-termism, only one major trophy in 30 years of management
AVB:
Strengths - tactical knowledge, long-term planning, 2 major trophies in 4 years of management (3 if you count the Portuguese Cup, which is borderline)
Weaknesses - man management, lack of experience, adept at keeping the media on his back.
So basically if there's someone out there who combines the strengths of both and doesn't have the weaknesses... we'll be onto a winner, and we'll all have nothing to argue about on this forum!
And of course a bit of Spurs pedigree in a manager would be nice too
I personally think Redknapp had more tactical knowledge than AVB. Arguably they were both lacking, but I didn't see any evidence of AVB having any whatsoever - just talk that he was a genious in this area, but no real proof. He had tactics, but they were not good tactics; or certainly were not applies correctly on the field.
Something good that they both had, Redknapp moreso, was Premier League experience so maybe that is something we should cuvet? I think the players were more scared of Redknapp than AVB too, and that was a good thing - we need someone with a bit more authority than AVB I think.
