Sky Sports News has been told by a source that Barcelona are interested in signing Juranovic to fill the right-back position.
The Croatia player is being looked at by two English clubs and a Spanish club.
Talks over a new contract were held by Celtic. The parties couldn't agree before he left for the World Cup.
Celtic will look to sit down with Juranovic again when he returns from his World Cup break next week, but they are bracing for bids.
After Croatia's World Cup campaign, Juranovic was given a week off and will be assessed for an injury that kept him out of the third-place play-off.
The signing of a Canada right-back by Celtic is already complete.
The defender will join the club in January after the Hoops paid an initial fee of 3.5 million dollars.
"We want clubs to look at our players, we want people to talk about our football club, and I think they are all positive things."
He is getting a lot of attention. Our players need to be noticed. They wouldn't be doing well if they weren't noticed.
I don't pay much attention to it. At the end of the day, I hope our players get the attention they deserve because we have good players here.

All of our boys did well at the World Cup and that is a reflection of how they are developing as footballers at our football club.
That's the most important thing. A lot of our players are getting attention and that is what we want.
Joan Laporta said last month that it would be hard for the club to sign in January despite the improved finances.
The club is in economic recovery because of the economic operations that were made.
We can't sign because of the rules of the Spanish league.
"We are trying to convince the league to be more flexible and allow us other interpretations that can make Barcelona even stronger."
