Without McBurnie and Montero, I can't see where their goals are going to come from. 8 games in and they've yet to score from a set piece.
We were able to find goals from most of our players last season, from a variety of situations.
I also agree to an extent with the other comment about Warnock having been there and done it, though Potter (maybe Harry would have more chance) has won promotions in Sweden. Not quite the same though.
