Benfica insist that they have received no formal approach from Celtic for Serbian midfielder Filip Djuricic.
The Bhoys' boss Neil Lennon is a long-term admirer of Djuricic, who only moved to the Portuguese side last summer.
However, Benfica have insisted that there has been no contact with the Scottish Premiership club regarding a move for the former Heerenveen player.
"We have not received any call regarding the transfer of Filip Djuricic," a club spokesman told Skysports.
Meanwhile, we are hearing from sources north of the border that Celtic are considering making a move for Middlesbrough's Rhys Williams - who Swansea City have held talks over.
