Barca celebrated as they clinched their 22nd La Liga on Saturday after their closest challenger Real Madrid drew 1-1 against Espanyol.
But, critics had earlier in the season taken Barca to task following their 7-0 on aggregate defeat to Bayern Munich in the semi-finals of the UEFA Champions League.
However, the club's director of football Zubizarreta remains happy with the way Barca have responded to adversity including manager Tito Vilanova being sidelined as he battles cancer.
"People were talking about the end of a cycle but we've won the main title again, the title of consistency," Zubizarreta said.
"The squad has been able to maintain a cruising speed with an incredible ability to compete".
On Sunday, the Catalans put the icing on their La Liga cake with a come-from-behind 2-1 win over Atletico Madrid at the Vicente Calderon. It pushed Barca to 91 points - a full 10 points clear of archrivals Real, who only have two games left to spare.
Proof, perhaps, that Barca do not need to abandon the tiki-taka football which has served them so well under former manager Pep Guardiola.
"We have to be clear where we're coming from," Zubizarreta said.
"We have to stick to our style and Tito accepted the challenge of maintaining it. We've tried to do that the best way we know how. We stick to this style even though it's sometimes not enough for us to win, like the day against Bayern".
"We have to keep on developing this idea and that's how we'll look at it at the beginning of the next campaign.
""If we look at our squad, 80% of the players that would interest us are already part of FC Barcelona. As always we'll analyse what needs to be improved but the base is solid and we've already got it".
Among the players expected to make an exit from the club in the summer include David Villa.
The Spain legend is no longer a first team regular at Barca and he showed on Sunday why there is plenty of interest for the player's signature across Europe.
Villa's shot forced Gabi to put the ball into his own net nine minutes from the end to seal Barca's 2-1 win over Atletico.
Earlier, Barca trailed through Radamel Falcao's opener but that was cancelled out by Alexis Sanchez on 72 minutes before Villa struck.
