If the win against Sociedad revealed a new Rooney, it also introduced to Moyes another player who might yet prove hugely influential. Shinji Kagawa started only his fourth game for Moyes and played the full 90 minutes. He was dangerous down the left, linking beautifully with Rooney and Ryan Giggs, and inventive when he moved inside to his favoured No.10 position.
"Everyone tells me about Shinji's ability and what he's got, but tonight was the first time I have really seen him," Moyes said. "I thought he played really well. When we put him in the No. 10 role, I thought he was very good."
This is truly a eureka moment. The shortfall in midfield creativity long identified at Old Trafford was always Kagawa's to fill, yet Moyes had been a reluctant traveller in this regard. Kagawa was not helped by the wide berth he occupied under Ferguson, a move ridiculed by his former manager at Dortmund, Jürgen Klopp, who claimed United had turned the two-time Bundesliga Player of the Year into a bit-part player.
He demonstrated with the hat-trick against Norwich at Old Trafford last season how great a range he offers in the traditional inside-forward role. If there is to be an accommodation when Robin van Persie returns, which is likely against Stoke tomorrow, then it is fair to assume Kagawa will be part of it, rather than a distrusted presence shunted into the margins.
By increments Moyes is edging away from the Ferguson template. Yes, these are players that were managed by Ferguson but the arrangement is shifting. At the back Moyes paired Phil Jones with Jonny Evans in the centre-back position he was bought from Blackburn Rovers to fill but so rarely has. And what a player he looked, a ball-playing defender, committed in the tackle.
Sociedad might have been modest fodder but it is not so much about the opposition for Moyes. It is more about how he sees United, how he pieces together the individual parts to make it his team. Wednesday was a step in the right direction.
