Benfica have issued a statement to the Portuguese stock exchange saying they have called off talks with Chelsea over David Luiz.
The two clubs have been locked in negotiations for the past week, and they had looked very close to striking a deal.
It is understood the main stumbling block has been how any transfer would be paid for, and now Benfica have seemingly decided to end the talks.
Benfica issued the following statement: "The negotiations between Benfica and Chelsea F.C with regard to the potential transfer of David Luiz, were concluded today without the parties reaching an agreement.
"Benfica are happy to be able to keep in their ranks a player with the sporting quality and moral shown by David Luiz.
"Unlike some news that had come up these last few days, David Luiz never tried to force his exit, he is an exemplary professional, worthy of the shirt he wears."
