Benfica are still finalising aspects of the deal to sell Paulo Bernardo to Scottish champions Celtic as they seek to protect themselves in the future.
Bernardo spent last season on loan at Celtic from Benfica and has been keen to head back to Parkhead.
Now Celtic are rapidly closing in on the midfielder and a transfer which will cost the Bhoys around £3.5m looks to be in the offing.
It has not been finalised yet though and, according to Portuguese daily A Bola, Benfica are finalising the last details.
