Chelsea are demanding a staggering £25m for Kevin De Bruyne, with Woflsburg leading the chase for the wantaway winger according to The Daily Telegraph.

The hefty sum has not put off the Bundesliga outfit, who held talks with Chelsea on Monday and are planning more discussions before the end of the month.
Woflsburg are thought to be keen to negotiate Chelsea’s asking price down and are determined to test the Blues resolve to hold out for £25m by submitting at least one formal bid in January.
Belgium international De Bruyne wants to leave Stamford Bridge this month and is keen to return to Germany, where he spent a successful campaign on loan with Werder Bremen last season.
But Chelsea are said to be reluctant to lose the 22-year-old permanently because they still believe the playmaker will blossom into a top player.
De Bruyne began the season in the Blues’ first team, starting the leagues games against Hull City and Manchester United before being dropped.
The Belgian has made just one Premier League sub appearance since, after reportedly angering boss Jose Mourinho with a poor showing in the Capital One Cup against Swindon Town.
