New footage has emerged of a flashpoint between Scott Brown and Alfredo Morelos.
The pair have clashed in the past, with the Celtic captain involved in an incident that got the Colombian sent off at the end of the 2018-19 season.
The Rangers striker scored in a 4-1 win over their city rivals on Sunday and once again the pair exchanged words.
And now footage posted by Twitter user @Aaron__1872 has revealed what was said between the two.
After an incident in the box that saw Kris Ajer go down hurt the Celtic man was straight on to referee Nick Walsh.
Brown can be heard saying asking for Morelos to be booked for a high foot.
The veteran says: "He's gone for his head! That's exactly the same as Callum McGregor's."
As the pair head back toward the centre circle Morelos can be seen making a crying gesture and saying "boo hoo" in a high pitched voice.
Brown then asks: "Ref? Is that a booking eh?".
Morelos was not booked in the incident and left the field in the 84th minute, while Brown was taken off just before the hour mark.
