Chelsea are pushing hard to sign Southampton defender Virgil van Dijk.
The Daily Star says the centre-back is high on Antonio Conte's summer shopping list.
Blues boss Conte is keen on a top-class addition to his backline.
John Terry is off at the end of the season, and although Andreas Christiansen is returning from a two-year loan at Borussia Monchengladbach, Chelsea are keen on adding another defender.
The Premier League leaders will be back in Europe next term and need to add depth to the squad.
Van Dijk fits the bill as a proven Premier League performer after impressing for Saints since his £11.5m move from Celtic in 2015.
The Dutchman's value has soared since then, with a £50m fee touted for the 25-year-old.
