Celtic are in talks with AEK Athens over the transfer of goalkeeper Barkas, who is rated at £6.5 million, according to the report.
The Scottish Premiership giants have had an initial bid of £3.5 million rising by another £1 million in add-ons turned down by Greek giants AEK, it has been reported.
The Daily Record has further claimed that Leeds and Montpellier are also monitoring the situation of the 26-year-old Greece international goalkeeper, who will be sold for £5 million despite him being rated at £6.5 million.
Leeds United or Celtic?
Leeds are a massive club in England and will be playing in the Premier League next season after clinching automatic promotion from the Championship this campaign.
However, Celtic are a giant of Scottish football and will be aiming to make it 10 Scottish Premiership titles in a row in 2020-21.
Between Leeds and Celtic, it will not be easy for Barkas to choose, although with the Hoops desperate for a new goalkeeper as they only have Scott Bain, the 26-year-old will get more playing time at Celtic Park in the immediate future.
