A lot of people here will be disillusioned when they see what Pellegrini can do in a top side when he is granted time and confidence.
I mean City here, where he will be obviously heading towards next season. The Arabs have shown patience with managers. They gave 3,5 years to Mancini to showcase his work. I assume they will give pretty much the same to Pellegrini.
And it is certain that he would have done the same or better compared to Mourinho. The season is not over yet, but lets say that Madrid wins Copa, and gets eliminated to Dortmund in the CL, which is most probable scenario. Mourinho delivered two cups and one LaLiga. Beside these, he left nothing to the team. Not a particular style, beside the quick counterattacking -which is not a style anyway and doesnot suit real-. Made a mess in the team, wanted himself bigger than the club and its history, was disrespectful towards club totems like Casillas, to the fans also..
His overall contribution was not so positive i reckon. His biggest achievement maybe is that he managed to de-throne Barcelona for a season and to win Barcelona 3 times in less than a year. But both of these were a lot more due to Barca's inner decline and fading, than any Real's magnificence.
Who would doubt that Pelegrini wouldn't be able to win LaLiga and 2 cups, if he had stayed in 2010 for 3 more seasons? Besides, he got so close in 09/10 with a team enjoying football, not ready for CL yet, but on the building.
AS for the rest, Heynkes would be an interesting choice. He is so good in bringing balance to a team, but i doubt if he would be able to re-build out of the ruins and the mess Jose will leave. He is best in taking a proto-design worked by someone else before (like Van Haal in Bayern) and perfecting it. But as i said before, Jose is not leaving any footall legacy behind.
Ancelotti is at its best when bringing the best out of star players (see both Milan and Chelsea). But his obsession with playing from the center and not the flanks is becoming hazardous as football has evolved a lot since 2003-2007 period..
Well, everyone taking Real job after Mourinho will have a very tough time with no titles for the first 1-2 seasons and a lot of complaint. Most know that... We'll see what happens. This summer there will be a lot of reshuffling around
