Isco has reportedly been offered a huge signing-on fee by Barcelona
Isco is out of contract at Real Madrid in 2018, meaning the La Liga giants could risk losing him on the cheap this summer should he not sign a new deal.
Barcelona, Manchester City and Tottenham are among a host of clubs linked with a move for Isco in the summer.
But Barcelona have stolen a march on their rivals to try and sign Isco, according to Spanish radio station Rac 1.

That would mean Isco remaining at Real Madrid for the 2017/18 campaign before joining up with Barcelona the following season.
