Xavi has issued a rallying cry to Barcelona as their Champions League hopes hang in the balance following Tuesday's 0-0 draw with Benfica.
The Blaugrana missed the opportunity to seal their progress to the knockout stages of the competition, despite a dominant performance at Camp Nou.
Although Xavi became the 13th consecutive manager to avoid defeat in his first Champions League game in charge of Barca, his side were unable to break down a stubborn Benfica.
The goalless stalemate was only the eighth that Barcelona have recorded in 133 home matches in this competition, while they have mustered just two goals from their opening five games.
They remain second in Group E and two points ahead of their Portuguese counterparts, but face runaway leaders Bayern Munich in two weeks' time with their fate yet to be decided.
Xavi insists his side will travel to Germany with a positive mentality.
"We were far superior to Benfica. If we had scored, we would be talking about a good match," the Barca head coach said.
"We take a point that means very little. We have one day left, and we have to go to Germany to win.
"We have one goal in two games [since I took over] and we have scored it from a penalty. It is clear that we have to be more effective.
"You have to go to Munich to win; we are Barca."
Ronald Araujo
Barca did have the ball in the net through Ronald Araujo in the 83rd minute, but the defender's volley was ruled out for offside.
The Uruguay international was pleased with the mentality demonstrated by the hosts, but admitted the result left a bitter taste in his mouth.
"We missed the goal, which was the golden key to qualify," Araujo said. "The attitude was very good, but they were very tight in defence.
"There is a bitter taste because we wanted to win the three points here, in front of our people, but we have to win now in Munich."
