He did. I watched the first 70 mins of that. Ballard did OK on the right of a back three with a five in front, wing backs dropping in and Jonny Evans (first half) & Tom Flanagan alongside. But he was playing in a very deep set up and wasn't being exposed to holding a high line as a two with full backs who aren't full backs even further up like he might do here (unless things change).
Haaland got in behind him in the first minute but his attempt was cleared off the line. Settled after he clobbered him in the back of the head in the 10th and put him out of the game briefly. Looked OK on the ball and organised his bit of the pitch, and he can kick long. Which is what I think might be what NC has mainly looked at with both the new CB's before the defending part. Only downside was he miss-timed a sort of diving header on the corner that ended up in the net as an OG off a teammate. Not sure what he was trying for really with that but just one of those. A full 90 minutes in that environment should hopefully help him be ready for whatever is next here, whenever the next game is.
