Virgil van Dijk was clearly in good spirits after Liverpool's latest win as he played an amusing prank on teammate Alisson during a post-match interview.
The Reds beat Red Bull Salzburg on Tuesday to secure their path to the Champions League knockout stages.
Goalkeeper Alisson spoke to the media in the tunnel after the match, while van Dijk stood to one side and flicked the lights on and off to distract him.
The Brazilian soon realised what van Dijk was up to though, and called him out on it as the Liverpool defender immediately burst out laughing.
Both men played their part in the win, ensuring the opposition drew a blank in a 2-0 victory - their first away clean sheet in 11 games.
Alisson was called into action early on, making a good double save in the opening minutes, before denying hotshot striker Erling Haaland later in the half.
His opposite number at the other end, Cican Stankovic, was also in inspired form, but his good work was undone in just two minutes.
First Stankovic came flying out of his net to thwart Sadio Mane, who chipped the ball past him for teammate Naby Keita to head into the unguarded net.
Failing to learn from his first error, Stankovic rushed out in an attempt to steal the ball from Mohamed Salah, who rounded the keeper and found the far corner from an acute angle.
The win ensured Liverpool's defence of their European title continues as they enter Monday's draw for the last-16.
Speaking of their clean sheet, Alisson told Liverpoolfc.com: “It was just a matter of time and of focus.
“The last two games, we were focused for the full game. Even if they had chances we were there, the defenders were there and I was there to help the team.
“We just need to keep going with this focus because we know our quality and we know what we can do on the pitch when we put in our whole intensity.
“You need to do that for 90 minutes – it’s hard, we know, but I think we showed we can do this.”
Meanwhile van Dijk reserved special praise for captain Jordan Henderson, whose ball in behind the Salzburg defence led to Salah's superb finish.
van Dijk said: "He created the second goal with a great pass and always works so hard for the team.
"We all appreciate what he does for Liverpool, both on and off the pitch. He's a leader."
