Pastore has been linked with some of Europe’s biggest clubs in recent years, including Manchester United, Chelsea, Arsenal, Manchester City and Real Madrid.
Gazzetta dello Sport reports that Barcelona are willing to match Pastore’s £35million price-tag in the January transfer window.
Palermo president Maurizio Zamparini told Gazzetta dello Sport: “I want to keep him and I’ve already turned down an offer from Real Madrid for €25 million.”
