Liverpool are challenging Manchester City for Napoli midfielder Piotr Zielinski.
Zielinski, 27, scored 10 goals last season as Napoli narrowly missed out on a place in the Champions League.
Calciomercato reports Liverpool and City have both contacted the Italian club about signing the 27-year-old.
The Premier League giants are trying to bolster their stocks ahead of another Premier League title race.
Jurgen Klopp is searching for a replacement for Gini Wijnaldum, who has left the club for PSG.
Zieliński has impressed in his five years with Napoli, having joined from Udinese in 2016.
