Isco is brilliant; his close control is magnificent, he moves forward between the lines and creates room for the others to exploit. Insane two-foot dribbling, his passing could become a bit better if he wants to reach the level of Iniesta/Silva (not that they are totally similar players mind). Isco is just 25 years old, he can easily play for Real Madrid the next five or six years. I guess up until now he has just been that guy who came from Malaga, not a shining star like Bale. However, the tables have turned and I really doubt Bale will start the Champions League-final even if he is fit. I am so glad Isco didn't end up at Arsenal or Liverpool over the last two years, they would have gotten a gem on the cheap - he most likely wouldn't have gone there anyway.
That is kind of the thing as well, I think Real Madrid are sick and tired of Bale's injuries - and with age, I guess it is only going to get worse. In his 4th season, Bale has played 30+ league games only once and over the last two seasons he has 42 league games in total. Do I want Bale at United if he cost 60M? Sure - but again, I think his injuries would only increase with age. No player gets a lot of injuries and then suddenly just stops getting them...
