André Schürrle's transfer from Bayer Leverkusen to Chelsea is close to completion after the Bundesliga club's general manager said a fee has been agreed, with Kevin de Bruyne moving in the opposite direction on loan.
Schürrle, who is understood to have agreed personal terms with the Blues, is on international duty for Germany in the USA and will likely head straight to London to finalise the deal following his release from Die Mannschaft.
The 22-year-old is set to join the Europa League winners in a reported £20 million deal, with Belgium international De Bruyne spending a season on loan in Germany
Schürrle was linked with a move to Chelsea last year
"We have reached an agreement with Chelsea," Wolfgang Holzhauser told the Rheinische Post newspaper.
"They are going to buy André Schürrle for a specific fee and, in return, they will loan De Bruyne to us for a year for free.
"I expect Chelsea to stand by what has been agreed."
De Bruyne's involvement was key to the agreement being struck, but speculation linking the player with Champions League runners-up Borussia Dortmund had thrown the deal into doubt.
