The Brazilian places the Catalan side amongst the best teams in the history of the sport:
"I've been watching this Barça side a lot lately and they're like Santos were in my heyday, or the great Benfica, Ajax, AC Milan and Real Madrid sides. They all set the standard in their day," he said.
"The key to their success was the fact they had settled line-ups over a long period of time. Don't forget that Barça is the core of the Spanish team. There's a connection there, just as there was between Ajax and the Dutch national team all those years ago and between Santos and Brazil."
