Chelsea's proposed move for Bayer Leverkusen's Andre Schurrle is in danger of falling apart due to Kevin De Bruyne's reluctance to leave the Blues until he knows who the new manager at Stamford Bridge will be.
Schurrle has agreed to a five year deal with the Blues, according to the German press, after Chelsea finally convinced Leverkusen to part with their star forward for a reported fee of £20 million.
De Bruyne, who has spent the season on loan from Chelsea at Werder Bremen, has been offered Leverkusen in efforts to smooth on-going negotiations for Schurrle's transfer in a cash plus player deal.
However, a proposed deal has been complicated, Express report, as the Belgian international would now like to see who succeeds Rafa Benitez as the Chelsea boss before deciding to leave the club permanently.
De Bruyne's agent Patrick Koster has also discussed his client's reluctance to cut his ties with the Premier League giants until they are fully aware of the situation. "We have an open relationship, so there have been talks," Koster told Voetbal International.
"We will wait and see who the new coach is."
The former Genk youngster hasn't just impressed the Leverkusen's hierarchy with his impressive performances this season, but a number of other team across the league too.
Champions League semi-finalists Borussia Dortmund have also been credited with interest, heightened by the recent announcement that their own diminutive attacker Mario Goetze has agreed to join Bayern Munich at the end of the season.
However, Leverkusen have found themselves in the driving seat, as they have looked to capitalise on Chelsea's keen interest in Schurrle by demanding the coveted De Bruyne as part of the deal.
De Bruyne officially signed for Chelsea in January 2012, joining up with his new club later that summer after completing the remainder of his season with former club Genk.
But after just a number of weeks with his new teammates, the attacking midfielder was sent out on loan to Bremen, where the Belgian has played an integral role for the club this season.
