I actually had been meaning to post for a a few days about our xG under Ole and having come here to do so, it seems others already had!
I think the metric is a good way of adding some nuance towards assessing our performance under Ole so far. Essentially so far, I think:
- Ole has demonstrably improved the team. We're scoring more (goals), creating more/getting more chances (xG), conceding less (goals against) and giving fewer chances away (xG against)
- Ole has demonstrably improved the mood of the club and the players. This is important. Aren't happy players more likely to play well? They'll have more confidence to convert chances and fight that little bit harder at the back to make it more difficult for the opposition. The manager is making his own luck here.
- Ole has perhaps been fortunate to get the points he has done so far. We're walking away with three points from very close matches more often than we could normally expect. We need to start beating lesser teams in a more convincing fashion, where we can expect to win a greater percentage of the time. We're winning a lot of games by the odd goal, where a bad referee decision or an individual error would cost us. We need to mitigate the potential impact of that variance. If we'd otherwise win 3-0, we don't care if the referee fecks up once. Dropping points means a whole lot more than it used to for chasing a league.
In summary, I think Ole has done great so far and I want him as my manager. He's improved the team and made it a joy to watch again.
I don't however think United are at City or Liverpool's level week in and week out, and we would still have to improve a lot to expect to challenge for the title next season. Otherwise, we would need a whole lot of luck.
Note: With xG, reading the narrative of a match is so important. xG is less effective at telling you who should have won a particular match, but is better at assessing whether a team were effective in a given scenario. For example, if a side is 2-0 up after 10 minutes away from home against City, and they only concede 0.6xG for the whole match, they deserved to win and defended really well. It doesn't matter if they only 0.3xG themselves. They were 2-0 up and needed to not just concede.
Likewise, if we go down 1-0 to Southampton early on Saturday, and then create 2.8 xG over the course of the game whilst giving away little at the back, it will show that we would have deserved to and expected to have scored and probably won the game, regardless of whether we did or not.
