The Reds take on Manchester City this weekend looking very different to the side that faced the Austrians tonight. 3 Red Bull Salzburg wonderkid – and Man Utd target – Benjamin Sesko celebrates scoring against LiverpoolCredit: Getty 3 Jurgen Klopp’s men underwhelmed in AustriaCredit: Getty Mo Salah, Virgil van Dijk and Trent Alexander-Arnold were benched as Jurgen Klopp fielded an experimental starting line-up. Liverpool beat Manchester United to the signing of Darwin Nunez from Benfica earlier this summer. But it was another Red Devils goal that stole the show on Wednesday night. Teenage striker Benjamin Cesko has been linked with United in recent days. The Slovenian, 19, confidently fired Salzburg into the lead just after the half-hour against the Reds. He left Ibrahima Konate for dust after a smart one-two with Okafor and smashed it past Adrian. And then he produced an outrageous piece of skill at half-time as he showed he would not be overawed by his illustrious opponents. Nunez had already hit the post and Salzburg were undone when star man Sesko headed home Fernando on the stroke of half-time.

Both teams had chances as Klopp made the changes at half-time and Firmino played in Diaz to score with seven minutes remaining. But unfortunately, the offside flag was up again. Klopp called on Salah, van Dijk, Alexander-Arnold, Thiago and Roberto Firmino in the second half after an impressive display from Uruguayan Nunes. 3 Sesko, 19, was the star of the show in AustriaCredit: Getty Roberto Firmino came off the bench at half-time but couldn’t do anything to change the game The Brazilian striker’s future is in doubt with Italian reports suggesting the Reds are in advanced talks with Juventus over a £16million move. Firmino, 30, has just one year left on his contract and has rejected the Reds’ mandate since Nunez’s arrival from Benfica in June. The Merseysiders are reportedly considering letting him go as long as they can sign a replacement. And 55-cap ace Firmino is keen to play regularly, so is primed for Brazil selection ahead of this winter’s World Cup in Qatar.
