When journalist and transfer analyst Fabrizio Romano tweeted about the likely departure, he instilled worry in the club’s fans.
Juranovic is said to be attracting Premier League interest after a good season in Glasgow, when he helped Celtic win the Scottish Premiership and League Cup, as well as excelling on the international stage with Croatia.
“Croatian national team right back Josip Juranovic is expected to leave Celtic FC this summer as many clubs are following him,” Romano tweeted.
“Juranovic is attracting interests from Premier League clubs too after great season for club and country.”
The 26-year-old forward signed a five-year agreement worth £2.5 million last summer after arriving from Legia Warsaw.
A deal like this for Juranovic, who has played both right and left back, is a steal, and if he is sold, he will certainly command a far greater price.
Last season, he played 32 times for Celtic in all competitions, winning the Ekstraklasa in his first full season in Poland.
In the last two years, the defender has earned 15 of his 20 Croatia caps.
Juranovic spoke on his future with Celtic earlier this month, expressing his satisfaction with the club.
“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.”
