Southampton have condemned the "abhorrent" racist abuse aimed at teenage midfielder Alexandre Jankewitz on social media after their Premier League loss to Manchester United.
The 19-year-old Swiss youth international was sent off inside 90 seconds of his debut start for the Saints, who went on to suffer a record-equalling 9-0 defeat.
Jankewitz subsequently became the latest in a string of players to be subjected to sickening online abuse, with monkey emojis and racist terms directed at him on social media.
Southampton are liaising with police over the matter.
"Southampton Football Club can confirm that it has identified a number of posts on social media directing racial abuse at our 19-year-old midfielder Alex Jankewitz, following last night's result at Manchester United," a statement from the club read.
"Abuse of any form will never be tolerated at Southampton.
"Our club prides itself on its inclusive nature, and supporters who stoop to such abhorrent and archaic standards are not welcome as Southampton supporters, or anywhere else within football ..."
Hampshire Police said in a statement to Hampshire Live that they "are aware of reports of racist abuse on social media directed at a Southampton Football Club player".
Online abuse towards footballers has been in the spotlight over the past week, with West Midlands Police arresting a 49-year-old man on suspicion of racially abusing West Brom's Romaine Sawyers.
Chelsea defender Reece James shared vile messages he had been sent, while racist terms and monkey emojis were left on recent Instagram posts by United duo Anthony Martial and Axel Tuanzebe.
Their Old Trafford teammate Marcus Rashford has also been abused, prompting an investigation from Greater Manchester Police.
Such incidents place further scrutiny on social media platforms as the UK Government plans to introduce new laws on online abuse in 2021.
