Bayer Leverkusen winger Andre Schurrle fears his proposed move to Chelsea is set to collapse.
The London Evening Standard says Schurrle, 22, is believed to have already agreed terms on a five-year deal but the two clubs have yet to finalise his transfer.
Leverkusen are still demanding to take Kevin De Bruyne, who has impressed while on loan from Chelsea at Werder Bremen, as part of the £20million deal.
Chelsea would prefer to loan out De Bruyne for another season but the player is starting to question whether he has a long-term future in London.
With delays persisting, Schurrle is concerned that the transfer will be called off.
