The Italian champions’ assault on him during the summer of 2015 failed to materialise, although according to La Gazzetta dello Sport, they are now ready to reignite their interest.
In recent days, Inter have also been linked with a move to bring him back to the Stadio Giuseppe Meazza but the Bianconeri are determined not to be beaten in the race for the midfielder’s signature.
The 24-year-old moved to the Estadio Santiago Bernabeu in 2015 for a fee of €40m and to convince the Champions League holders to sell him, it would likely take an offer of €10m-€15m more than that.
Juventus previously made contact with his entourage last summer and as recently as last week, Allegri has signalled that he would prefer to have Kovacic over other alternatives, such as Lorenzo Pellegrini and Giacomo Bonaventura.
Additionally, it is being reported in England that a move to Turin for Kovacic could in turn lead to Sami Khedira departing the Allianz Stadium to join beaten Champions League finalists Liverpool.
