RB Leipgzig chief Max Eberl is adamant Josko Gvardiol isn't for sale.

The Croatia defender is a target for Chelsea and Manchester City this month.

However, Eberl insists RBL holds all the cards.

"By activating the option to extend the contract we have the reins of the deal in our hands. The club has done an exceptional job," said Eberl.

"We have no interest in giving him away in the summer."
