Real Madrid coach Carlo Ancelotti is happy seeing Isco succeeding at Real Betis.
Isco will face former club Real Madrid this weekend.
Ancelotti said: He's playing really well, he's rediscovered his best form and I'm delighted for him.
"He's a player who has contributed and continues to contribute a lot to football. He's been through some tough times but he's come out the other side.
"He'll be one of the players we have to keep a close eye on tomorrow."
