Iniesta was optimistic of proceeding through to the Champions League finals in May, though quick to note that the remaining teams pose a serious threat to their ambitions.
Speaking to AS after the match, the Spaniard said: "We played well, we had a good feeling and we're happy to be in the quarters. We'll see what happens in Friday's draw.
"The fans the difficulty of the Champions League but we are closer than a few hours ago. We know how hard it is to win and go through. We must keep a cool head and go game by game."
Barcelona captain Puyol however was confident of reaching a successive spot in the finals and believes that the squad has re-discovered the form that made them unstoppable last season.
"We have recovered and now the best is still to come. We play for two very important titles."
Brazilian full back Alves was happy with the work rate of the team and echoed the words of his captain, stating it was more like the "real" Barcelona as he looked forward to Friday's draw.
"It was the work and effort of the whole team. It was a game like the real Barcelona. We play with this spirit, enjoyed by all. We are on the right track. It is a very difficult competition and it's hard to win. The team is getting there and hopefully get past the next round and be closer to our goal," he remarked.
"We are very happy. The work today was remarkable. In this competition there are no weak opponents. People have this dream in their head. If you're defending a title you're usually the favorite, but I think each game in the Champions League is like a World Cup. We must go again, looking at each team and see how the draw goes.
