Chelsea boss Andre Villas-Boas feels a move away from Stamford Bridge will prove the right long-term decision.
A lifelong Porto fan, the 33-year-old recalled when his former club moved into the new Estadio Dragao eight years ago.
He said: "When Porto left the old stadium to go into the new stadium - the Dragao - nobody liked the name, nobody liked the site, nobody liked the stadium, and nobody liked the idea of moving.
"Because the historic presence of the old stadium on that site meant something enormous for the fans.
"But if you go back to Porto now, there is not one single person who remembers the old stadium.
"Everybody is in love with the new stadium. It's a beautiful stadium, it's a magnificent site and everybody is happy with the move that was done.
"Because it took us into the future, brought us more revenues in the end, and made us play in a magnificent stadium.
"That's my experience of the past. I'm not in a position to say how the fans will react, and how they are reacting.
"In the beginning, disappointment regarding the loss - or not - of an historic site can mean something.
"But eventually, if we move or not, things will be for the best for sure."
