The Belgian motioned toward the Broomloan crowd alongside teammate Nedim Bajrami before the celebrations were abruptly halted.
Nicolas Raskin is rarely far from the chaos on Old Firm day.
The Rangers midfielder thrives on the battle with Celtic and often finds himself right in the middle of the drama. Raskin, 25, has been involved in several heated clashes with Hoops captain Callum McGregor over the past few seasons.
Over the last week, the Belgian has also gone toe-to-toe with Mexican defender Julian Araujo. It didn’t require a lip reader to understand what the two were yelling at each other during Sunday’s Scottish Cup encounter after yet another confrontation.
There’s also little affection between Raskin and the Celtic supporters.
In footage recorded by FootyAdventures, Raskin could be seen taunting the travelling fans in the Broomloan Stand after Emmanuel Fernandez appeared to have forced Rangers ahead from a corner.
While Raskin’s teammates swarm Fernandez and celebrate near the roaring Sandy Jardine Stand corner, the Gers’ chief agitator quickly turns his focus to the frustrated Celtic crowd.
Raskin, together with Nedim Bajrami, is spotted gesturing toward the green-and-white faithful — pointing and laughing as the supporters respond furiously.
However, the duo were quickly left red-faced moments later when VAR stepped in to rule out the goal, with Fernandez clearly using his hand to nudge the ball over the line.
The Scottish champions ultimately had the last word when the match was decided by a penalty shootout, with Tomas Cvancara stepping up to send the Celts into the semi-finals.
