A 2nd rate manager, clueless in Europe, incapable of building on title winning sides, easily foxed by mediocre opposition sides. An ideologue trapped by his own idiosyncracies. So yeah. If he is able to set his own standards, yes he is brilliant surpassing all his own expectations. Give him another 5 years or maybe 10.
Meantime back in the real world. about as many trophies as George Graham.
