He is one of three changes Klopp has made to his side in Naples, for a clash which the manager believes “if you don’t defend with all we have then we have no chance.”
They will support Salah, Mane and Firmino in attack, with the front three in excellent form heading into this Group E opener.
Speaking at his pre-match press conference on Monday, Klopp stressed that this would be a difficult test as Liverpool aim for a strong start back in Europe.
“We want to be as consistent as last year, but play our football from this year. It’s just ‘do your best’ all the time,” he told reporters.
“Last year we learned from one game to the next game and we have to use that experience because if you don’t defend with all we have then we have no chance against Napoli, they are so strong.
“They are stubborn in a positive way. They play football, they break lines, they have good counter-attacks, they are creative.
“I enjoy it when I analyse Napoli. I like to watch them.”
