The Croatian international was recently linked with a move to the Premier League by renowned transfer specialist Fabrizio Romano.
Now, according to Sky Sports, Atletico have joined the race as they look for a new right-back.
Kieran Trippier left for Newcastle United in January, while Juranovic’s fellow Croatian Sime Vrsaljko is set to join Greek giants Olympiakos when his contract expires, leaving 33-year-old Daniel Wass as Diego Simeone’s only right-back option.
Juranovic had a brilliant season for Celtic, having arrived last summer for a bargain price of £2.5million after helping Legia Warsaw win the Polish league.
The 26-year-old was a key part of Ange Postecoglou’s side which won the league and League Cup double. The defender featured at both left and right-back.
He is under contract until 2026 and will command a substantial fee. It has been reported he is valued by Celtic at £15million.
Juranovic has previously stated his happiness at Celtic.
"I enjoy Celtic," he said. “I started my career, I won the championship in Poland – now in Scotland. I can't wait to get back to Glasgow again for the new season. It is great for me at Celtic.
"We’ll see, it’s not up to me. I’m happy at Celtic.”
Celtic are on the lookout for a new left-back with Alexandro Bernabei set to join and challenge Greg Taylor for the position, while would mean it is Juranovic and Anthony Ralston competing for the right-back berth.
