Liverpool have received another big selection setback ahead of their Group B clash with Porto in the Champions League this evening after it was revealed that Trent Alexander-Arnold hasn't travelled with the first-team squad.

What's the word?

According to the Liverpool ECHO, the 22-year-old right-back is out of the Estadio do Dragao clash after picking up an unknown issue.

The report states that: "Alexander-Arnold was not part of the Reds’ squad that flew to Porto on Monday ahead of their Champions League Group B clash on Tuesday evening.

"The right-back had taken part in open training at Kirkby earlier in the day only to not be among the party that disembarked the team coach at their hotel in the evening."

Liverpool have not released any details on Alexander-Arnold's absence, but it's likely to mean either James Milner or Neco Williams will fill in on the right-hand side of defence.

Jurgen Klopp will be gutted

News that Alexander-Arnold will play no part in this evening's fixture against Porto will leave manager Jurgen Klopp feeling gutted.

The Liverpool boss had already confirmed that Thiago Alcantara would miss the game due to his calf injury, so the news that another one of his stars will now be unavailable is a big blow.

The England international has started the season in impressive fashion, recording three assists in just six appearances in all competitions, playing a pivotal part in Liverpool's unbeaten start to 2021/22.

Fellow academy graduate Williams, sidelined for the past month through injury, is fit again and was part of the 22-man squad that travelled to Portugal, meaning the 20-year-old could pick up his first minutes of the campaign.

Klopp could also turn to experienced campaigner Milner, who put in an eye-catching performance when he deputised for the ill Alexander-Arnold against Crystal Palace earlier this month.

However, as capable as those two players are, they're not of the same standard as Alexander-Arnold, so Klopp will not be happy that he has to play his first European away game of the season without his first-choice right-back.
