A brace of goals from Lionel Messi and one apiece from Xavi and Fabregas saw the Catalans claim their second title in three years with a most emphatic victory.
The European and Spanish champions had been under pressure to prove just why they are being talked of as one of the finest sides in the history of the game but the former Arsenal midfielder insisted that they never felt weighed down by the burden of expectancy.
“We’re always relaxed,” Fabregas told reporters after the game. “This team loves pressure, this team loves these kind of games and that’s why they won as much already in these last four seasons.
“They don’t have to prove anything to anyone anymore. All we have to do is just keep believing that we can do more.”
Indeed, Fabregas claimed that there is no chance of Barca’s remarkable run of success negatively affecting the players’ desire to successfully defend their La Liga and Champions League titles.
“We are very young players and I still believe that we will keep this hunger,” he reasoned.
“Obviously you cannot win every single year, that’s impossible, but we have to do the best we can try to do it.”
On a personal level, Fabregas, who joined from Arsenal over the summer, admitted that he is relishing the chance to play alongside the likes of Messi, Andres Iniesta and Xavi.
“It’s great, they are the best players in the world,” he enthused. “They create so many spaces and so many chances.
“For me it’s a very, very special day. It’s been a special four months, I’ve won three titles and we are doing very well in the league, in the cup [Copa del Rey] and in the Champions League as well.
“All I want to do is keep going and keep improving and try to win as much as I can and be the best player I can be.”
Dani Alves, who has played a key role in Barcelona’s current era of supremacy since arriving from Sevilla in 2008, believes that he knows the secret to the club’s success.
"I think the difference from Barcelona to the others is that besides the fact that we have great football players, we work hard,” he argued.
“So when you put these two things together, you have the group that we have now.”
Meanwhile, the Brazilian full-back also had some kind words for his compatriot Neymar, the highly-rated Santos forward who struggled to make an impact in the game in Yokohama.
"Neymar is ready to play anywhere,” Alves said. “He is a spectacular, special player and once again I say it: the doors are open for him.”
Neymar has been repeatedly linked with a move to Spain over the past 12 months, with both Barca and Real Madrid said to be keen to sign the striker.
