Harry Maguire escaped a red card after appearing to kick out at Michy Batshuayi during Manchester United's clash with Chelsea.
Maguire was bundled to the floor in front of the Chelsea dugout during the first half, before his stray leg and upturned studs scraped down Batshuayi's groin.
Batshuayi then tumbled to the ground himself in agony, prompting angry protests from the Chelsea bench, while Maguire claimed the contact was accidental.
Referee Anthony Taylor referred the incident to VAR, which was quickly dismissed, but debate raged on Twitter over the centre-back's intentions.
Former Chelsea midfielder Cesc Fabregas felt Maguire was lucky stay on the pitch and tweeted: 'Red'.
Numerous fans also took to social media to slam Maguire. A user with the Twitter account @360Sources, tweeted: 'Harry Maguire with the dumbest foul of the season, he could've easily been sent off. VAR with another shocking decision.'
Another fan, David Paztor, was equally scathing of Maguire: 'How is that Maguire kick NOT deliberate? VAR having one, again.'
Understandably, Chelsea fans were adamant of Maguire's guilt. Twitter user @UptheChels tweeted: 'How on earth has Harry Maguire not been sent off there? I give up with VAR. It’s got to go.'
Minutes after the incident United took the lead in first half injury-time when Anthony Martial headed home from Aaron Wan-Bissaka's right-wing cross.
