Steven Gerrard has gone on the offensive as the Rangers manager admitted he was becoming frustrated at what he views as a lack of consistency in judgements from the SFA.
The call follows Alfredo Morelos' latest suspension after he was hit with a charge for stamping on Hibs defender Ryan Porteous, which carries a three match ban due to a previous suspension for violent conduct.
While the club opted not to contest the charge, the manager insisted there was a lack of consistency from the authorities when it comes to such incidents.
But to which incidents could Gerrard be referring?
Record Sport takes a look at four big flashpoints that may be on the mind of the Rangers manager.
Odsonne Edouard v Dundee United

The Celtic striker was in the spotlight at the end of 2020 after a meaty challenge on Peter Pawlett. There were calls for the Frenchman to receive retrospective action after the tackle in the 3-0 win over Dundee United, however no further punishment was issued by the governing body.

In the heat of the New Year derby Shane Duffy cut down Ryan Kent in the middle of the pitch, appearing to catch the winger late on the back of the leg. A melee ensued after the clash but the centre-back was only handed a yellow card, when pundits after the match admitted they expected Bobby Madden to reach for the red. No further action was taken by the SFA following the challenge.

The Aberdeen striker caught Borna Barisic high and late in the first half of the 2-1 win for Steven Gerrard's men. With the Dons already down to 10 after Ryan Hedges walked early on, referee John Beaton flashed the striker a yellow card but many felt it could have easily been the second sending-off before half-time. Derek McInnes quickly hooked the striker after the poor challenge. The SFA took no further action against the striker.
Darren McGregor v Rangers

Last month Darren McGregor escaped an SFA punishment for a flashpoint with Glen Kamara, in the same clash which saw Morelos handed a three-game ban for a 'stamp' on Ryan Porteous. The Hibs stopper stood on the Ibrox midfielder's calf as he lay on the ground, and was booked. Following a look by the Hampden panel, no further action was taken.
