Liverpool' s defensive woes continue to grow, with full-back Andy Robertson now the latest player to potentially face a stint on the sidelines.

The left-back tweaked his hamstring on Thursday night during Scotland's Euro 2020 play-off victory over Serbia, a triumph which saw them qualify for their first major tournament in 22 years.

“I think I was next, but my hamstring had seized,” Robertson told Sky Sports when asked to discuss his nation's penalty shootout victory.

And Scotland manager Steve Clarke has given Liverpool boss Jurgen Klopp more food for thought by admitting the 26-year-old could miss this afternoon's Nations League clash with Slovakia.

“Andy Robertson is the most doubtful out of the ones who have a wee question mark over them.”

Robertson's potential hamstring injury will only serve to increase the injury headache Klopp is currently enduring.

Liverpool - the defending Premier League champions - are currently in the midst of a defensive crisis following a series of injuries to key players.

Kop stalwart Virgil van Dijk will miss the remainder of the season with a grade three anterior cruciate ligament tear, which he suffered in the Reds' 2-2 draw with Everton last month.

Joe Gomez is expected to miss the majority of the campaign with a knee injury, although the Merseysiders are optimistic he'll return to action in a few months' time.

Gomez's England team-mate Trent Alexander-Arnold is also on the sidelines with a calf injury, although he's expected to be back in the starting XI in just under a month's time.

Andy Robertson could be set for a stint in the treatment room

Should Robertson indeed need time in the treatment room, Klopp will need to have another long, hard think about what his back-four for next weekend's clash with Leicester City will look like.

It's likely he'll call on some of Liverpool's academy prospects to fill the voids, something he hasn't been afraid to do during his five-year tenure at Anfield.
