Jurgen Klopp says Napoli will be emotional facing Liverpool again in the Champions League group stage.
The two giants are joined by Genk and RB Salzburg in Group E after Thursday's draw.
A 1-0 victory over Carlo Ancelotti's side at Anfield sealed the Reds progression to the knockout rounds last season, and Klopp says the Italian side will not have forgotten that night.
"Napoli again! I don't know how often I've now played against Napoli, but they're obviously a very experienced side," Klopp told Liverpool's official website.
"Napoli are just a really good side. The home game we played [in last season's Champions League] was one of the best games we played because it was so rock solid.
"In the pre-season games, when we won 5-0 in Dublin [in 2018] I was not interested in the result. Now this year we lost 3-0 and that's not too interesting, but you see how good they are.
"Carlo has such experience and has won the competition so often [three times]. When they went out last year, it was pretty close, so they will remember that and it will be emotional, I am pretty sure."
