Actually, quite a lot...Argentina, Uruguay, Brazil, Italy and Germany have done it more than once! Also, Spain didnt win 3 consecutive big trophies because they lost the Confederations Cup twice, both in big fassion. Besides, Spain was dominant for 4 years, because after the Euros they have fallen for the 3rd or 4th favourite spot (behind Brazil, Germany and maybe Argentina). Not that it diminishes their accomplishment, but when you analyse the best and most dominant NTs of all times, Spain falls very short on the list. My point is, there were many more teams in history that dominated for a longer period of time and with much stronger opponents!
