Of course he did, he was excellent.
Think you are missing the point here.
Justin is a really good player with plenty to offer. I'd go as far as to say he's a better player than Doyle. But he's a very different player and the team will have to adjust.
As an example, we like to switch the ball quickly when it gets to Faes and Doyle out to the opposite winger. We've done it loads, and had success. Justin, a right-footed player on the left, is unlikely to hit those raking passes over to Mcateer or Fatawu like we've seen Doyle do many times. Alternatively Justin offers additional threat going forward so it may mean we have to play a more traditional "back four" setup at times.
We could also see Hamza in that position.
