Jurgen Klopp has maintained Liverpool will keep their options open regarding recruiting a left-back as cover for Andrew Robertson during the summer transfer window.
The Scotland captain, one of the club's standout players during a remarkable 2018-19 season, underwent minor surgery on his hand after picking up an infection from an insect bite.
He will be back in training soon and will travel out to the United States with the squad, but Klopp is still deciding whether to scout the market for an understudy to the 25-year-old for the new campaign or to promote from within.
