Chelsea have completed the signing of 21-year-old Marco Palestra from Atalanta.
Palestra joins on a seven-year deal through to 2033. The fee is up to £47 million ($62m) including add-ons.
The defender spent last season on loan at Cagliari and made 37 appearances in the Serie A, he scored once and provided four assists during the 2025-26 campaign. He was also named Serie A Defender of the Season.
The Italian international, who can play at right-back or wing-back, has been brought to suit new manager Xabi Alonso's preferred 3-5-2 system, which utilises players who will stretch defences high up the pitch.
