Chelsea are in talks with Feyenoord striker Salomon Kalou.
Kalou, 20, is the younger brother of Ivory Coast captain Bonaventure Kalou, who plays for Paris St Germain.
"We have given Salomon an authorisation to talk with Chelsea," said Feyenoord marketing director Chris Woerts.
"We've been in talks with this club for some time over Kalou. It's going in the right direction but he hasn't reached an agreement yet," added Woerts.
