One of Jurgen Klopp’s main issues during his tenure as Liverpool boss has been finding a suitable left-back.

Since the German’s arrival Alberto Moreno has fallen down the pecking order, with Klopp preferring to play the more reliable James Milner there.

Milner, has made 31 appearances for the Reds this season and he has done more than fill in.

Despite being right footed he has looked solid defensively and good going forward, as well as providing an experienced head to an often unsettled back line.

But the 31-year-old has come unstuck when faced with the top wingers in the Premier League, and despite his seven goals this season, Liverpool realistically do not want to have to rely on him next season as well.

So with Klopp’s reluctance to play Moreno, one of these three top class left-backs should be at the top of his shopping list come the summer window.

Benjamin Mendy

Monaco’s French left-back gained many plaudits following two fine performances v Manchester City in the Champions League, and has become a regular in Monaco’s XI since signing from Marseille last summer.

The 22-year-old has made 30 league and cup appearances this season, scoring once and laying on ten assists for his teammates.

Despite arriving at Monaco for just £5.3 million last summer he would likely cost much more now, and Liverpool would face stiff opposition from the likes of Chelsea.

Mendy is quick, strong and reliable and could fill the Reds’ left-back hole perfectly for years to come – if Klopp could secure Mendy’s services it would be a real sign of intent from Liverpool.

Jetro Willems

PSV’s 22-year-old fullback has been linked with Liverpool for some time now and he would provide a top solution to their left-back woes.

Since making his debut in 2011, Willems has become PSV’s first choice left-back and has made 26 appearances in all competitions this year, scoring two goals.

The Dutchman also has international pedigree having already represented his country on 22 occasions, and would provide the Reds with real pace on the left, along with a threat going forward. He’s scored twice this season in 21 league games.

Gael Clichy

The Frenchman’s Manchester City contract is up in the summer, so he could provide Liverpool with an experienced head on the cheap.

The former Arsenal man has made 30 league and cup appearances for City this year, scoring twice, showing that he still has something to offer at a top side.

The only drawback would be Clichy’s age – he’s 31 – so would only fix the left-back problem for a couple of years.

But Clichy is an experienced Premier League player and has won three titles in his career. There might be younger options out there – but in terms of quality and price there is no one better.
