I was shown some stats at work today that Celtic are being treated far more leniently than other teams by the refs. When Collum previously reffed them this season they managed to commit 18 fouls and the solitary booking they got was Soro in the 86th minute. They are averaging 14 fouls per card against 8 fouls per card for teams playing them. We on the other hand are the most harshly dealt with team in the league.
To compare that to something outside of Scotland West Ham have the highest fouls per card in the EPL at 10 fouls per card then it's Chelsea at 8. Italy is AC Milan on 9. Spain is Sociedad on 8.4. Germany is Bayern Munich on 12 then RB Leipzig on 10.
