Chelsea are reportedly keeping close tabs on highly-rated Hellas Verona defender Marash Kumbulla.
Kumbulla has enjoyed a breakthrough season under Ivan Jurić, making 19 appearances across all competitions.
According to Corriere dello Sport, Blues manager Frank Lampard is unconvinced by his current defensive options and will look to refresh his backline this summer.
Verona are currently sixth in Serie A and Kumbulla – alongside Amir Rrahmani – have conceded just 15 goals when partnered together.
Andreas Christensen is expected to leave Stamford Bridge while Kurt Zouma is also fighting for his future in west London.
Everton and Napoli have also expressed an interest in the 20-year-old who could cost around €30m.
