A few games but i would say current Isco is better than his RM version. He fits team like Betis more.There was a season when one or two of Madrid's big name players got injured and he was great for them.
But beyond that was always generally good.
Isco was always a great player but during Real madrid time he got a lot of hate from the fans because he slowed down the game play too much with holding the ball
Imo his best seasons at Real was 14/15 and 16/17 ( he and CR were a great duo that season)
He, Pedri and Olmo together would be a very strong midfield for Spain🔥
Pedri, Isco and Olmo would be suspect defensively
