Chelsea are taking a serious look at RB Leipzig defender Josko Gvardiol for the summer.

The Blues need to make changes to their back line, as both Antonio Rudiger and Andreas Christensen are leaving on free transfers.

Rudiger is heading to Real Madrid, while Christensen could join their rivals Barcelona.

According to Goal, 20-year-old Gvardiol is one that Chelsea believe can become a mainstay in their back line for years to come.

He can play on the left side of a back three, which appeals to coach Thomas Tuchel.

The Blues are also considering Jules Kounde of Sevilla, Presnal Kimpembe from Paris Saint-Germain, and Joes Gimenez of Atletico Madrid.
