The 19-year-old full-back was probably earmarked as one of Liverpool’s weak spots by Pep Guardiola before kick-off, but his inexperience definitely didn’t show and he kept Leroy Sane tucked away in his back pocket.
In the end, the Reds went on to win 3-0 in the Champions League quarter-final first-leg at Anfield, and look to have one foot in the competition’s last-four – but this match will have a lot more significance for Alexander-Arnold.
His lung-bursting runs from deep – combined with his relentless marking job on Sane – definitely signalled tonight as a breakout performance for the youngster – and it wasn’t missed by the club’s supporters on social media:
trent alexander-arnold has been good. wonder did klopp fire him up by repeatedly asking him “are you shitting yourself?” in front of the other players

Absolutely buzzing for Trent Alexander-Arnold tonight. So many doubters after a few individual mistakes recently, but he was immense against one of the best wingers in European football.

Trent Alexander Arnold what a fucking game. To come back from all that criticism that he can’t defend and do that tonight, what a player and can go on to be an all time great

What did you think of his display, and how he coped with the extreme pressure?
Could he be a late contender for an England World Cup spot?
What do you think?
