The Blues are set to sell striker Michy Batshuayi this summer with Timo Werner close to joining the club.
Batshuayi joined Chelsea from Marseille four years ago for £40 million but has struggled to hold down a regular place in the team.
Despite scoring 25 times in 77 games for the Blues, he has always been down the pecking order and has had loan spells at Borussia Dortmund, Valencia and Crystal Palace.
Premier League side West Ham are believed to be interested in the Belgian international. Crystal Palace and Newcastle United are also reportedly interested in the 26 year old.
According to Daily Express, Chelsea are holding out for £40 million for the transfer of Batshuayi, an amount interested clubs are unwilling to pay for the striker.
