Incoming Chelsea boss Jose Mourinho may insist on keeping Kevin de Bruyne next season.

The London Evening Standard says De Bruyne's future is key to Chelsea's transfer activity as Bayer Leverkusen want to sign him as part of the deal that will see Andre Schurrle move the other way.

However, Chelsea are still hopeful of using him as bait to persuade Borussia Dortmund to sell striker Robert Lewandowski to them, rather than Bundesliga rivals and their opponents in Saturday's Champions League Final, Bayern Munich.

It is understood Chelsea are very unwilling to sell the Belgium international and would prefer to send him away on loan again, should Mourinho not want to include him in his plans just yet, as they did to Genk and Werder Bremen respectively.
