Barkhuizen is certainly too far away from goal at the moment. He's easily one of the best finishers at the club, and shouldn't be on the touchline, a) because he can finish if played more central and b) he isn't a tricky/skilful winger so out wide he won't be beating players on his own.
I think the defensive crisis has distracted a discussion from the real problem which, as I said on the matchday thread, I think is scoring goals.
Other than a few games in September, we've been struggling to score all season. In 3 of our last 5 home games, we have drawn a blank. We lack composure and quality when moving the ball forward and the decision making when playing the final ball is often terrible.
Very worrying I like Alex Neil
We need to add quality in this area (and other areas) in January but we also need to get a bit more out of what we've currently got. As already discussed Barkhuizen is too wide. The left-sided role clearly isn't getting anything out of Robinson who played off a big man last season.
I don't see Neil changing his system anytime soon, but a few tweaks need to be made going forward or we'll continue to look very toothless in front of goal unfortunately.
