The former has made his wishes to leave Old Trafford this summer apparent in recent weeks, with Erik ten Hag instead deploying Anthony Martial to spearhead his attack throughout pre-season. Darwin Nunez was of interest to the recruitment team in Manchester, but Liverpool managed to acquire his services.
Nunez played for his new team in Salzburg on Wednesday night, but he wasn't the striker who caught the eye of spectators. Instead, it was a certain Benjamin Sesko who stole the spotlight.
Just 19 years old, Sesko scored the only goal of the match to deliver a 1-0 victory for Red Bull, leading a counter-attack from deep and finishing with impressive composure.
Despite standing around 6-foot-4 and providing a real presence in the penalty box, Sesko was mobile enough to pose a threat behind Liverpool's defence, with Ibrahima Konate and Joe Gomez presented with the tricky task of keeping him quiet.
The Slovenian proved to be a handful for Klopp's outfit. In the 43rd minute, he assumed possession near the touchline and was closed down from either side by both Curtis Jones and James Milner, and there appeared to be no way out. Sesko somehow managed to escape the sandwich by improvising with a skilful spin, shielding the ball from Milner while backheeling it away from Jones.
He upheld the core principles of Red Bull football in his performance before being substituted at half-time, demonstrating a willingness to press and harry opponents while also leading counter-attacks with pace and directness.
The large majority of players his size simply aren't capable of covering excessive ground or playing on the shoulder of defenders, but Sesko showcased his well-rounded skill set by doing exactly that.
Salzburg are masters of unearthing gems. A whole host of talents have passed through their club as youngsters from Sadio Mane to Naby Keita to Karim Adeyemi to Erling Haaland.
Although Sesko has only recently emerged as a prospect in the public eye, he isn't too dissimilar to the latter in many ways, with Haaland deemed to be so unique because of his ability to combine speed with power, height and a clinical edge when presented with opportunities to score.
Sesko has a lot to prove before being talked about in the same vein as the Norwegian star, but the two possess comparable profiles and both have emerged from the same cultured scouting network in Austria.
