Trent Alexander-Arnold set up Liverpool teammate Diogo Jota with a sublime whipping cross as the Reds lead Atletico Madrid going into half-time.
The Reds welcomed the defending champions of Spain to Anfield on Wednesday night for their Group B Champions League clash.
And Liverpool made the breakthrough in the 13th minute after Trent picked out Jota with an exquisite cross from the right-hand side.

Jordan Henderson played the ball into the path of an unmarked Trent, whose first-time cross caught out the Atletico defence by complete surprise.
Jota waited for the ball to arrive from three yards out before he fired a header past Jan Oblak from an unmarked position.
“Another day, another assist for Trent,” one fan tweeted.

Someone else posted: “Another brilliant assist for Trent.”
While a third Twitter user wrote: “Obviously not just saying it because of that assist there, but it baffles me that some people don’t think Trent is the best RB [in the world].”
And a fourth added: “The numbers alone are impressive, but it’s the quality of Trent’s assists that set him apart from the rest.”
Trent ensured Liverpool went into half-time with the lead after setting up teammate Sadio Mane, who slid the ball past Oblak from close range.
