I don't think so, Spain had a lot of problems to break down a parked bus. If Barcelona with Messi couldn't win against Madrid and Chelsea in 2012 and Inter in 2010 I don't see why Spain would have won.
In 2010 they were simply unlucky to be defeated, though Mourinho parked the airbus.
By mid 2012, Barca had began to run out of steam, and by 2013, they started to depend more and more on Messi, not the team as a whole.
Chelski simply couldnt be defeated that year, btw, the Gods had decided that they would win CL that year.
