I think that's a very fair post, and perhaps closer to how mine should have looked.
That said, the fact that Ronaldo scored nearly double the goals needs to be analysed further. We won the treble, so I'd guess he played more games. He also took all of our penalties while Spurs didn't get any. I'd say the gap could be a bit less if those factors didn't exist. Not to mention the fact that he was in the best team in Europe, who generally dominated most games.
Yep, was thinking this would be touched upon.
It's definitely something to take into consideration, though I don't think it makes up for twice the productivity - it really cannot be stressed how enormous an achievement that was at the time given the role he played. I would even say that Ronaldo was more restricted in his role then than Bale too, actually; Bale now is a lot more likely to go through the centre, where as Ronaldo would usually end up in the centre via a wide position off the ball. I thought that was a shame in context of his previous season but not unexpected given that Tevez and Rooney were often both playing.
I think one thing to consider about the 07/08 team is just how much Ronaldo dragged us in an attacking sense at times. We had much better control over games back then than our current team (a significant factor admittedly), yet Tevez and Rooney probably had two of their worst seasons to date. Likewise, Scholes and Giggs had pretty poor seasons and many were predicting they were on their way out. We did have some great performances at times but it was the sheer efficiency and also magic of Ronaldo that became by far the main emphasis of our attack. The reason I think his productivity has increased in Madird in fact is because, in players like Ozil and Di Maria, I think he's playing for a team more suited to his talents, and not because he is a lot better now than he was then. We only had the Madrid Ronaldo for one season, yet in that one season a whole host of our top players were playing some way beneath themselves, with some of them taking up the central areas that he has been more prone to occupying at Madrid.
Nevertheless, as you rightly point out, United > Spurs in terms of the control that the two teams had over games. The difference that makes is something that can never be proven and can only really be estimated, though I do think it's worth considering the context of Ronaldo's season even if he was playing for a double winning team. That Ronaldo wasn't too different from the current one, meaning that the discussion doesn't become all that different from questioning whether Bale is better than the current Ronaldo. I don't think this is necessarily a perfectly logical way to look at the argument, but it's something to consider given the noticeably clear difference between the two players these days.
Edit: I think there's another thing to consider here, and that is the special sort of mentality it takes to be so influential in a team full of stars. It takes a hell of a personality to play so freely for a top team and there's no guarantee that someone of Bale's lesser technical ability would be like that amidst United/Madrid players. Sometimes it's forgotten that being by far the best player in a team often makes it easier to excel on an individual basis, and gives you a confidence that you're not guaranteed to have if you're one of many.
I can't believe he said Gareth fecking Bale is physically superior to Ronaldo. What the hell is he on?
