People here go in circles and too defenite of their opinions like they are afraid to be seen as wrong. Lets just say what do you see when you see Isco play? Kind of player?
For me Isco is a faciliator type of playmaker instead of the direct decisive final play kind. Kind of playing style and role thats died out in a wing/psuedo forwards/inside forward obssessed football. Besides his flaw of overdribbling, in overall his playing style is close to a true nr 10 Iniesta or Zizou who both wouldnt allways make the direct assist (someone like James is alot more direct) everytime but open things up with ingenuity and skill in the build up just before decisive final third, things you dont see in stats (for example look at what he did in Malaga, you had to watch them/him, because his few assists or goals wouldnt tell you how insanely influential he was at 19). Just like its already illustrated you dont go by goals/assist stats to phantom the greatness of someone like Modric. They are players who need to move with lots of freedom, the kind thats not given much anymore since so few play with 4-3-1-2 in the hole approach anymore in current game (funnily enough we are only top team who would if we go back to that Allegri favoured approach).
Teams arent willing to put the entire burden of creativity and attacking impetus on a single player, rise and fall on a nr 10s moods or consistency (I get it, because it used to annoy me to watch how inept we looked at times when Zizou was completely off, became better team with Nedved and Camo sharing burden). So these players have been pushed wide or downwards, hence why he becomes CM for Real (Zizou would prolly become LW or CM in current systems). And a young Iniesta spent half a decade in Barca being wasted on the wing before he got the comfortable role thats molded to his skillset later on and he became world class. Not sure if you guys remember a young Iniesta vividly, but he was very inconsistent or very weirdly used off the bench in attack, best example of how patience pays off big time...Something organisations like Real never have (this is why we have Morata in our books), and hence you will most likely see him flourish outside then with them after their usual rehash everything with new toys habit kicks in.
Just to make it perfectly clear. I'm talking playing style and not comparing his abilities to them even though he has great qualities, but lets not forget this guy is still 23-24. ALOT of room to grow with time and trust/proper role. And alot of chances to make some here eat humble pie. Its not about world class this or that, its just weird idea to see someone like Isco play and not see the insanely obvious sheer quality he has to his game. And how much better it can be when its fully developed.
