Celtic troll Rangers

The club have trolled Rangers on Twitter, posting a tweet that includes a photo of Kenny Miller celebrating a goal he scored against Rangers during his Celtic days.

Of course, Miller now calls Rangers home. So Celtic fans were always going to love the tweet.

The tweet is now pertinent because Miller, along with teammate Lee Wallace, has been suspended by Rangers after a furious outburst aimed at manager Graeme Murty in the dressing room after Sunday’s loss.

Per Record Sport, Miller was furious with Murty’s handling of the match and let his feelings be known at full-time.

The report adds that Rangers now plan to sack Miller.

Miller, 38, was an unused substitute at Hampden Park on Sunday, much to the frustration of his wife Laura.

“Fact - Kenny is a big game Old Firm player but hey, who am I to have an opinion,” Laura Miller tweeted.

Murty admitted that the dressing room after the match was emotional, which he expected after such a disappointing defeat.

"There was anger, frustration, all the sorts of emotion you would expect from a changing room that has just gone through that," he said, per BBC Sport.

"There should be frustration and anger. It is just about turning that into positives and energy to power you through to the end of the season rather than allow it to be disruptive."

Meanwhile, Celtic will relish the retweets they’ve received on their tweet.
