Yes - I've heard this before, but it doesn't seem to tally with matches I've watched, so I checked.

Not as good as you might think, certainly nowhere near the top. In fact one of the lowest.
- Our xG ration last season (proportion of total goals scored that were as a result of set plays) was 0.21. There were only 4 teams with a lower score than this.
- The teams with some of the highest proportions of set piece goals (0.41) were Millwall & Rotherham, neither of whom were very good last season.
- We scored 16 goals in total from set plays. This is a slightly better stat, putting us joint 7th with actual goals (rather than a proportion of overall goals) with Bristol C, Forest & Blackburn.
- However, when you look at goals scored per shots ratio (set plays only) our score (xG) is 13.42. 15 teams had a better conversion rate than this...
..which brings me back to my original post - find a player that can hit a top corner & bend round a wall consistently and you get a better score. I see nothing in those stats or from what I watched last season to show we are trend setters in set pieces.
