The Blaugrana are currently four points behind Real Madrid heading into week 30 of the Primera Division and the gap could be down to one point by the end of the weekend if Barcelona beat Betis and if Los Merengues lose against Sevilla.
Gudjohnsen is confident that his side can go all the way to knock Real off top spot.
“I am sure that we can win La Liga and we must think that we can do it,” the striker told Marca.
“I’m certain that there will be plenty of opportunities for us to trim the gap to Madrid.
“We can put huge pressure on Real if we win on Saturday, If we win all the pressure will be on them.
“However it’s important that we think about us and that if we win all our games then we would be the champions. “I think that we can make history this season and we need the three points.
“We are professional and we have the hunger and desire to win, there are still two titles that we can win."
Gudjohnsen also spoke about Ronaldinho’s troubles thus far this season.
“I think Ronaldinho is unhappy because he does not play, however I would prefer not to talk about the subject,” he said.
Barcelona will be hoping for maximum points against Betis and no doubt their fingers will be crossed for Sevilla causing an upset against Los Blancos.
