The Old Firm ref row has raged on relentlessly with both sides of the Glasgow divide going at it hammer and tongs.
Tam Scott, Fife, emailed: "What do the Rangers fans want? Connor Goldson stops the ball with both hands going towards goal. Morelos pushed the defender with both hands. They can’t get away with it all the time." Charles Buchanan fired in his email: "Why do Rangers complain about decisions against them all the time? Didn't hear them complain when Celtic didn't get a penalty for Goldson's great save and them getting a penalty for Salaka standing on Starfelt's boot."
Dennis Martin meanwhile had something to say on spot-kicks, and silverware merits for them: "Huge congratulations to Rangers on being the only team in the SPFL not to have conceded a penalty after 31 matches, despite the lottery of VAR. It is a pity that in only 10 European fixtures they have conceded 4 penalties. They are also equal top with Aberdeen and Hearts with 9 penalties awarded, but with 7 fixtures to play there is still time to win this 'title'. Celtic are not so fortunate as they have conceded 8 penalties and awarded only 6. Not very impressive for a team at the top of the league."
