Netherlands international Noa Lang launched into a sweary rant on Sunday after Club Brugge's 2-2 draw with local rivals Cercle Brugge.
The 23-year-old, who was chased by Arsenal earlier this season, called his teammates 'f***ing p***ies' as he lamented his side dropping points 'every f***ing week' in a video shared on twitter.
It came as he followed manager Scott Parker down the tunnel after the game, with pressure mounting on the former Bournemouth and Fulham boss after winning just one of his nine games as manager.
Club led twice in the game, Lang scored the opener after 18 minutes, but gave it away both times as they were eventually undone by a 78th minute equaliser
Parker joined the Belgian side as the start of the year after he was sacked at the Cherries, and became just the fourth English manager to lead a team in the Champions League knockout stage when they faced Benfica last week.
