Yildiz - along with Thuram and Bremer - is one of the few unsold players in the Juventus squad, with general manager Comolli and right-back Chiellini having been working for weeks to renew the Turkish star's contract.
The stated aim is therefore to protect the number 10 from offers from other major European clubs, with Juventus in close contact with the player's family and manager Jorge Mendes to extend his deal until 2030, with a significant salary increase of up to €4 million net plus bonuses.
The green light for Yildiz's contract renewal has also come from the owners, with John Elkann personally taking steps to remove the Turkish attacking midfielder from the transfer market.
The 2005-born star is at the heart of Juventus' project, although he continues to attract interest from major clubs abroad. The latest among them is Barcelona, ??with coach Flick in particular impressed by Yildiz's technical skills and potential, according to reports in Spain.
The Turkish number 10 is said to be at the top of the German coach's list of targets, and he has reported him to president Laporta and sporting director Deco as a primary target in the transfer market.
Barca will try to sign Yildiz, but are aware of the difficulties involved and Juventus' desire not to part with the player.
The attacking midfielder himself is also happy in Turin and would not consider leaving the "Old Lady" this summer.
However, Barcelona are reportedly not ready to give up and will continue to pursue Yildiz for the future, delaying any potential move until the next January transfer window.
