Italian champions Juventus are lining up a move for ex-Stoke midfielder Steven N'Zonzi, who is also on Chelsea's radar.
The Frenchman was a mainstay of Sevilla's midfield this season, racking up 35 appearances in LaLiga.
The Spanish side finished fourth in the table and reached the last 16 of the Champions League with N'Zonzi an integral part of that success.
Chelsea were heavily linked with a move for the 28-year-old in December as manager Antonio Conte attempted to bolster his squad in time for the title run-in.
But the midfielder stayed put at Sevilla and penned a new deal with the club in January which does not expire until 2020.
