I can't find the study, so I'm not sure. I think you can fairly approximate it using a basket of different stats - goal attempts, possession, things generally considered 'good' in football. Of course it's not perfect as a team that has perfected counter-attacking might be the better team despite not doing much after they went ahead; but if applied across a number of teams and leagues it should give you an idea.
Yeah, I find that, when talking to casual football fans at least, it leaves one open to the simplistic response of "I prefer to score goals than make pretty passes" and such. It's probably a niche interest, but I'd like to see a lot more of this sort of broadly scientific analysis done into football on Sky and ITV and such, rather than rolling out people who used to play the game and watch it a fair bit now.
But I don't see any reason to believe that the wins will stop, except for a major glut of injuries, of course, or Fergie going back to the stupid team selections which have hindered us at times. I think it's about time people on here started gaining a bit of confidence.
I have never been as certain about United winning a title as I was going into this season. We've gone about it in a weirdly cackhanded way, but we're getting the points and the goals I expected, so I remain as confident as I was three months ago. I think we're really, really good, and if we could sort out the system and get Vidic back to the player he used to be, I suspect we could be great.
But what do you expect when you have a squad which gains 89 points, and then add Robin Van fecking Persie to it?
The wins might stop because we don't get as lucky as we have done so far. I think continuing with the current form and getting to 92 or 93 points would represent an outstanding achievement, but unless we keep getting lucky we'll need to improve to maintain it. We're probably not going to be able to keep falling behind and then coming back late on, sometimes other teams are going to defend better, sometimes referees will cost us points, sometimes VP and Rooney will have bad days or the midfielders won't be able to get the ball to them, and so on.
In particular injuries to our strikers similar to what has happened to our defenders in the early part of this season would kill us, the defensive injury crisis isn't such a problem for us because, apart from Vidic, whose current abilities are unknown, all of our defenders are at roughly the same level, but there's a massive chasm between Rooney & VP compared to Welbeck & Hernandez, if the former two get injured it's a massive blow.
Saying that, I don't want to give the impression I'm being pessimistic, I'm not, I think there's a good chance we could maintain this points/games ratio, provided Vidic returns, provided our defence improves, providing at least one of our world class strikers stay fit, all of which are pretty likely. Sustaining the current ratio though, that is the optimistic view, the idea that we'll improve on the current form once Vidic comes back and when other players settle in better, that's pretty much a fantasy. As far as results go our current run is about as good as it's going to get.
