The Reds lost Alberto Moreno this summer after opting to let the Spaniard leave on a free transfer and so they could be on the lookout for cover for Andy Robertson.
Robertson has been one of Liverpool FC’s most important players since his arrival at Anfield from Hull City in 2017.
The likes of James Milner and Joe Gomez have been used at left-back and they could be called upon again next season.
But Klopp was giving nothing away when asked if he is looking to bring in reinforcements in that position ahead of the new Premier League season.
Speaking in an interview quoted by ESPN FC, Klopp said: “I said already, we have to think about everything, and in the end maybe we do nothing, but we will see.
“As you can imagine, we will have a look at all the things around us.
“Of course we have lost a left-back [Moreno], and today you saw two pretty young ones [Larouci and Lewis], while James [Milner] has played it and all that stuff.”
Robertson made 11 assists in 36 Premier League games for Klopp’s side last season.
Liverpool FC are aiming to go one step further in the Premier League next season after they finished in second place and just a point behind champions Manchester City last term.
The Merseyside outfit did win their first major trophy under Klopp last season when they beat Tottenham Hotspur 2-0 in the Champions League final.
