Liverpool new boy was a second half substitute.
Liverpool boss Jurgen Klopp has a big decision to make ahead of the Premier League season over who will start at left-back.
James Milner featured regularly last season in the position, while former Sevilla left-back Alberto Moreno staked his claim with an excellent display against Bayern Munich this week.
Last night new signing Andrew Robertson got an opportunity to show what he could do, featuring as a half-time substitute in the Audi Cup final against Atletico Madrid.
The game ended in a 1-1 draw, with Atletico winning on penalties.
Robertson acquitted himself well, and almost scored a winner at the end when presented with a chance in injury time.
He may not have scored it but the fact he was in the position was a demonstration of his attacking intent.
The Scotland international was not the headline grabbing signing many Liverpool wanted when he joined from Hull City, but last night's display was encouraging and he could go on to win over his doubters.
Here is a look at how Liverpool fans reacted on Twitter to Andrew Robertson's performance...
Well impressed with what I have seen from Robertson over his two appearances. Looks like he is fitting in nicely #LFC— Steve (@Kopsquad7) August 2, 2017
Robertson isn't a shrewd signing or a bargain. He looks a 8 million player #LFC— Dhruv Arora (@astrometal) August 2, 2017
Wicked ball from Robertson. He puts in some quality balls you know, lovely left foot. #LFC— Mo (@CoutinOhOhOh) August 2, 2017
Robertson and Moreno > Milner at LB all day everyday #lfc— Alexander Ogbechie (@alexanderOG) August 2, 2017
Robertson done well there, composed defensively, and gets involved going forward. Decent crosser of a ball #LFC— jonathan jenkins (@jonshinko76) August 2, 2017
Good signs from Robertson going forward. Good technique, awareness and links up well. Need to se more defensively #LFC— Pedro Almeida (@PedroAlmeida_93) August 2, 2017
