Chelsea have approached Bayern Munich to understand if defender Jerome Boateng is for sale this summer, Metro has reported.
The 28-year-old endured a below-par campaign with the German giants after suffering a number of injuries.
And according to Italian website Tutto Mercato Web, the Germany international is keen on making a move to Stamford Bridge.
Southampton's Virgil van Dijk continues to be manager Antonio Conte's primary summer target to strengthen the defensive department but Boateng is an alternative option.
The Blues will officially open talks with Bayern Munich in the coming days according to reports in Italy.
