Chelsea have had a £20million bid for Real Madrid star Isco rejected, according to Express Sport.
The 23-year-old is a target for a number of clubs including Arsenal and Juventus.
According to reports in Italy, the Serie A champions want the player to be included in the deal that would see Arturo Vidal join the Spanish giants.
Coach Massimiliano Allegri is an admirer of the Spaniard and would be delighted to have him in his squad.
Isco joined Real Madrid for £21m in the summer of 2013. He played more than 100 games for the club, scoring 17 goals in all competitions.
