I didn't catch him being great live yesterday, I noticed he made some mistakes (as players usually do), and thought he was sometimes out of position.
Then I thought he really shined as a LB, pushing forward and starting attacks. I thought his position change was key, and he played this position close to perfect.
Obviously then he scored his goal.
But watching this:

He really did look great. I think his positioning in this clip is exactly as I want for the most part. (I should keep in mind, though, these are his touches, maybe he truly was wrongly positioned a lot, when he didn't get the ball)
