A deal for Argentinian left-back Francisco Ortega is reportedly being 'explored' by Celtic this summer.
After lifting the Scottish Premiership title, competition for Greg Taylor appears to be a priority for Ange Postecoglou this summer.
Forgotten Boli Bolingoli looks set to bring the curtain down on his spell at Celtic Park this summer, and Velez Sarsfield star Ortega appears to be on the Parkhead wish list.
The Daily Mail report that the 23-year-old has been the subject of positive scouting reports and a deal is now being "explored".
Postecoglou has distanced himself from a deal for Iraq international Mohanad Jeahze in recent weeks, and Ortega could present a viable alternative.
Reports in Sweden report that Hammarby are preparing for a move for their full-back from Celtic and looking at replacements for Jeahze.
Interest in Ortega comes with the transfer floodgates set to open at Celtic with a permanent transfer for Jota seemingly top of the agenda.
The winger is set for further Parkhead talks when he returns from a holiday in Ibiza with the club set to pay Benfica £6.5million to secure the player.
The Portuguese side are set to have sell-on clause that could be as high as 30 per cent.
