Chelsea are struggling to find an agreement with Benfica for defender David Luiz.
The Mirror says Blues boss Carlo Ancelotti is desperate to land the 23-year-old centre-back and had been confident of signing him in a cash-plus-player deal.
Talks have stalled, however, because Benfica want £21.5m plus either youngster Jeffrey Bruma or Patrick van Aanholt.
Chelsea say that the Portuguese club can have one of the two players but only on loan, NOT on a permanent basis.
