Bereszynski joins Napoli from Sampdoria.

Napoli have reinforced their team in their pursuit of their first Scudetto in more than three decades by signing right-back Bartosz Bereszynski from Sampdoria.

Bereszynski joins from Samp, where he spent the previous six years, on an initial loan until July, with the option for Napoli to make the transfer permanent.

The 30-year-old Poland international has made 180 appearances in the Italian top division since the beginning of 2017, the sixth-most of any defender during that time period.

He will compete with Giovanni Di Lorenzo on the right side of Napoli’s defense, which is five points ahead of Milan at the top of the standings.

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.
