Mane is Klopp's best Liverpool signing says Jamie Carragher
It's been a fun few years since Jurgen Klopp took over as manager and we've signed some great players, many of whom will go down in history as Reds legends.
But the question as to which is his best signing - so far - is one which will have many answer. For former Liverpool player and Sky Sports pundit Jamie Carragher though, the answer is straight forward - it's Sadio Mane.
The Senegal captain joined the club from Southampton for barely £30 million in 2016 and has since gone on to become probably the team's most important attacker.
And Carragher told the Telegraph: "You could make a strong case obviously for Mohamed Salah, Virgil Van Dijk or Alisson following the incremental improvement that has coincided with each of their arrivals.
"But I still maintain that the correct answer to this particular question is Sadio Mane.
"So how do you define 'world class'? I judge it by thinking about a fantasy world starting XI and whether any given player would either get straight into the team or at least be in the best two or three in the world in their position.
"As left-sided attackers I would rate Mane, Raheem Sterling and Eden Hazard as currently the best, especially now that Ronaldo has become more of a striker and the struggles of Neymar since the World Cup.
"I also think that Mane is Liverpool's first genuinely world-class winger since John Barnes and the club's best wide left player for almost 30 years."
