Darwin Nunez is said to have stormed the tunnel after Liverpool’s 3-1 win over Bournemouth at Anfield.
For the second Premier League game this season, the 24-year-old has been left out of Jurgen Klopp’s starting XI.
And he wasn’t started against the Cherries until the 86th minute with the Reds 3-1 up.
The Uruguay international was given too little time to make an impact as Liverpool fought back from behind to claim all three points on Merseyside.
According to eyewitnesses at the game, Nunez, who joined Benfica last year in an £85m deal, made a hasty exit from the pitch.
One Liverpool fan tweeted: “Nunez straight into the tunnel full time, didn’t look happy. No idea why.”
Another posted: “Nunez very unhappy. Stormed in the tunnel. No idea what happened.”
A third added: ‘Nunez is not a happy bunny straight down the tunnel.
This supporter then commented: “Darwin Nunez not happy at all left the pitch at the whistle of his foot and went down the tunnel.”
Meanwhile, one fan watching simply said, “Nunez straight down the tunnel. Don’t look happy.”
Nunez has struggled for consistency since arriving last summer, with the forward scoring nine Premier League goals in his first season in England.
He has only found the back of the net four times in the top flight in 2023, with his last strike coming in April in the 6-1 win at Leeds.
