Vazquez struck in the victory on Sunday.
And he later remarked: "In other years it was difficult for us to win at this kind of stadium and that was where we threw away the LaLiga.
"This shows we are very well and we will be there until the end.
"If we lost in Pamplona, yes (doubts would return), but winning is the answer. We put aside any doubt. The team has shown a very good, supportive performance and has been very good.
"We are very good in the LaLiga, which is very important for us. And we will fight for the Champions League."
