Liverpool boss Jurgen Klopp made an interesting comparison between his striker Darwin Nunez and Robert Lewandowski yesterday.

Klopp has been upset at the criticism of Nunez since their season resumed.

Many pundits and fans stated that Nunez should have taken the chances that fell his way in the Carabao Cup against Manchester City and in the Premier League against Aston Villa.

"Going back to that time [when Lewandowski played under Klopp at Borussia Dortmund], I was sitting in a press conference and when I started playing Lewandowski the journalists asked me why (Lucas) Barrios was not playing," said Klopp.

"Lucas Barrios had scored 16 goals that season and was the number nine in our team.

"So Lewi started playing in different positions to adapt to different things, didn't like it too much. The Polish journalists were not too friendly with me because he didn't play number 10, he played in a 4-2-3-1 at 10. I thought at that time it made absolute sense to develop his game. So all different things.

"There are a lot of similarities (with Nunez) to be honest. Lewi would tell the same story, we had shooting sessions where he didn't finish off one. We had bets all the time for €10 - 'if you score more than 10 times I will pay you €10, if you don't you have to pay me'. My pocket was full of money."
