Brighton did as well, at pretty much every goal you can see 5+ players in the box... but yeah I'm pretty done with trying to sort this history revisionism out.
I'm just going to accept what has been very noticeble: people actually don't remember how Brighton played with GP in charge.
25 years maybe?
Always difficult to judge since two managers rarely have identical working conditions. Might have to wait until they both retire to see how they've coped with various challenges over their careers.
Deeper defense and more of the build-up happening on the own half to create spaces on the opposition (rather than occupying it and relying on combinations to lock up their defense).
Potter is more adaptive while RDZ is more interested in optimising one strategy.
