Real Madrid captain and Spain number one Iker Casillas has dismissed Barcelona's recent dominance as a "passing fad".
Barca have claimed the last two Primera Division crowns and the 2009 Champions League with a fluid passing style which has won them a new army of admirers.
But Casillas is adamant Mourinho's more pragmatic approach will pay dividends in the long term.
He told Marca: "We are able to stand up to them. We compare favourably with them and we are only a couple of months, perhaps a season away from them.
"This is the best Barca in history and they have been in fashion but this is just a passing fad.
"Mourinho is a very important addition for us.
"He is the ideal coach for his character and the way he expresses himself to the players. I think he will succeed at Real Madrid."
Madrid have not won a domestic trophy for two years but have started the new Primera Division season strongly.
They currently lie in fourth position, two points behind leaders Valencia and a point ahead of Barca.
