Xavi endured a miserable week as Barcelona boss last week after a 3-3 draw with Inter Milan was followed by a 3-1 defeat to Real Madrid in El Clasico.
The result in Europe hampered their chances of making the knockout rounds of the UEFA Champions League for a second successive season while defeat to their domestic rivals knocked them off top spot in La Liga.
Despite their well publicised financial woes, Barcelona splashed the cash in the summer transfer window, bringing in Raphinha, Jules Kounde and Robert Lewandowski for big money while Andreas Christensen, Marcos Alonso and Franck Kessie arrived on free transfers.
Xavi acknowledges pressure is mounting around his job but he is keen to remedy the situation.
"I think we've made a team to win titles," he said ahead of Thursday's game against Villarreal.
"I am excited, people give me encouragement. I have a mobile with so many messages that it seems like a family member has died.
"The transition was in the last half season. If we don't succeed, as the president said, there will be consequences, especially for me.
"I'm here to solve problems, and if we don't win, another coach will come. I'm not going to hide."
Asked when he might lose his job, Xavi replied: "Anytime, tomorrow. On the street, people raise their fists at me. But I am positive.
"We have lost at Madrid, and we can be knocked out in Europe. Well, I will keep fighting."
