Napoli have strengthened their squad in pursuit of a first Scudetto in more than three decades with the signing of right-back Bartosz Bereszynski from Sampdoria.
Bereszynski joins from fellow Serie A side Samp, where he has spent the past six years, on an initial loan until July with the option for Napoli to make the deal permanent.
The 30-year-old Poland international has made 180 appearances in the Italian top flight since the start of 2017, which is the sixth-most of any defender during that period.
He will provide competition for Giovanni Di Lorenzo on the right side of defence for Napoli, who are five points clear of Milan at the top of the table.
Both clubs confirmed the transfer on their official websites on Saturday, a day before the sides face off at Stadio Luigi Ferraris in Serie A.
Luciano Spalletti's men suffered their first loss of the season against Inter on Wednesday, but they remain the favourites to win the title for the first time since the 1989-1990 season.
