Chelsea and Borussia Dortmund are battling eachother for the signing of Toulouse defender Serge Aurier.

L'Equipe says Borussia Dortmund are chasing the 21 year-old Ivory Coast international Aurier and made contact with Toulouse last week.

Chelsea and Arsenal are also tracking Aurier leading up to the summer market.

A Toulouse source said: "Nothing is planned regarding Serge Aurier's sale. No decisions have yet been made."

Aurier recently said: "Moving abroad? I don't think it is too early.

"It is about trust, and reaching a new step, I am not scared to go higher."
