Stuart Attwell has refereed in the top flight & is currently a football league referee. Admittedly though he made a lot of errors in the premier league (including sending Caldwell off at City with the scores at 0-0) which is why he is no longer a top flight ref!!
You could also argue however that as the players at this level aren’t as good they make more error than premier league players & hence there are more mistimed challenges, handballs etc.. & that’s why there are more penalties being awarded – off the top of my head I can;t think of too many that Latics have given away that I would disagree with
