That's exactly the same as Callum McGregor's," he can be heard saying, per Daily Record.He was, of course, referencing the McGregor's foul that saw him sent off earlier in the game.Morelos was in the mood to troll his opponent as he made a crying gesture and saying 'boo hoo'.Brown, still trying his best to get Morelos a yellow card, told the referee while pointing at his opponent: "Ref? Is that a booking eh?".Watch the moment below:

Brown's protests were to no avail though as Morelos escaped a yellow card.

It's moments like these, as well as his brilliance on the football pitch, which have made Morelos a fan favourite.

But, judging by his comments in March, he may have played in his last Old Firm game.

"There are opportunities now for me because I have won the league in Scotland," he said, per the Express.

"One of my big dreams is to play in the English Premier League. It is one of the best leagues in the world and there are a lot of important players and important teams.

"So if the opportunity presents itself in my career, I am going to take it.

"It's a style of football very similar to Scottish football and I would enjoy it."

Rangers fans will not want to see Morelos leave this summer. But, if he does go, he will always be remembered with fondness at Ibrox.
