From Spain: Isco upset with Real Madrid; Juve ready to pounce
In fact, as stated by the newspaper AS, Isco is upset with Real Madrid and Solari for the lack of confidence, having not played as much as he would've liked since the new manager took over.
Therefore, he would also be ready to listen to offers in January, and the newspaper adds that he's already received a few proposals. One of the teams interested are Juventus, who reportedly are monitoring the situation of the Spaniard.
With that said, if the opportunity comes across, then they would be ready to pounce on the 26-year-old, although it would have to be on the right conditions.
