Erling Haaland might face charges from the FA due to his furious outburst that followed Manchester City's 3-3 draw with Tottenham on Sunday.
Dejan Kulusevski scored a 90th-minute equaliser for Spurs at the Etihad, denying the hosts a potential match-winning opportunity deep into stoppage time.
Haaland was brought down by Emerson Royal on the halfway line but recovered to pass the ball through for Jack Grealish. The English player seemed poised to advance towards the goal with only the goalkeeper to beat, but referee Simon Hooper blew his whistle and halted play for a City free kick.
Haaland was incensed by the decision, vehemently expressing his displeasure to Hooper before storming off the pitch in frustration.
Shortly after the match, the Norwegian international posted 'WTF' on X account, formerly Twitter, alongside a clip of the incident.
Although Haaland received a yellow card for his on-pitch outburst, further repercussions could follow if the FA deems his social media post a breach of Rule E3.1, which governs comments on social media or statements made in the media.
Earlier in November, Arsenal manager Mikel Arteta was charged under the same rule following his reaction to the Gunners' contentious defeat to Newcastle United.
Post-match, Pep Guardiola defended his striker's reaction and said, "His reaction was the same for 10 players," the City boss said. "The rules are you cannot talk with the referees or fourth officials, so we should have had 10 players sent off today. He’s a little bit disappointed."
"Even the referee — if he played for Man City today he would be disappointed for that action, that’s for sure."
"I make mistakes, players make mistakes. When Erling goes down, the ref said play on and after making the pass, he stopped the game," he maintained.
"I don’t want to criticise him. Sometimes on the touchline, I lose my mind, and my gestures are not proper, but we didn’t draw for that. Spurs are happy with a point, we are a little less happy," he concluded.
On the other hand, Haaland at least seemed to have calmed down sufficiently to see the funny side of the incident this afternoon.
Sharing an image of his face superimposed over Edvard Munch's famous painting, The Scream, he wrote 'Wtf that made me smile for the first time today'.
