Chelsea are interested in RB Leipzig defender Josko Gvardiol.
The Croatia international is expected to leave RBL this summer and has attracted enquiries from Tottenham.
However, Chelsea are also keen after it was confirmed Toni Rudiger will leave this summer when his contract expires.
"Thomas Tuchel is a big fan of Josko Gvardiol. He would take him immediately if he could get him," says Sky Deutschland's transfer expert Florian Plettenberg.
Gvardiol has a deal with RBL to 2026.
