As always, the truth isn't necessarily one thing or the other, it's a mixture and relies a lot on the context.
He has absolutely bought well, at least initially. Bought players for his style. Put square pegs in square holes. His style is very well coached into them, every single player knows what is expected of them. And that style is in many ways pefect for most games in Scotland...it even worked against Rangers until more recently when things have been a bit tighter, though they've still got results.
But his style doesn't work as well if we go back to 3 subs, as an example. So in that regard he's been fortunate. He's been able to outspend the rest by orders of magnitude, which again is pretty fortunate. He has failed in European football with this style, and failed pretty overwhelmingly. He has also had the luxury of Rangers dropping points where we really shouldn't, meaning even in games where they're not overwhelming the opposition, there is a lack of pressure and they inevitably get the job done. That's fortunate, though their domestic record can't be questioned, it is very, very good. But he clearly has no other option but to play that style, which means good teams can and have worked it out and he can't change it.
We'll see how he gets on at Spurs. If I was a betting man I'd go with what I said earlier in the thread - an initial good run followed by a quick and unrecoverable drop-off. If he's getting Spurs into the CL and winning a cup, I'll eat the leftovers of that poster's trousers from earlier in the thread.
