Barca still fighting for La Liga title
That run has trimmed Madrid's lead at the summit to just four points with the season's second El Clasico still to come.
Barca closed to within a solitary point following their 4-0 defeat of Getafe on Tuesday but the manner of Madrid's 4-1 win at Atletico 24 hours later has possibly handed the momentum back to Jose Mourinho's side.
Barca midfielder Sergio Busquets concedes the title remains Madrid's to lose but has vowed the defending champions will not relinquish their crown without a fight.
"The league will be difficult, but nothing is impossible," he said.
"They have the advantage. We have had these advantages before and in the end we've been champions.
"But the only thing that interests us is winning every game we play.
"If we give our all then we will have an opportunity, but we are thinking game by game.
"In Levante it will be very difficult. We will do everything we can to get another three points."
Barca make the trip to the Ciutat de Valencia in good spirits and the mood in the camp will have been enhanced this week by the news striker David Villa's rehabilitation from a broken leg remains on track.
The Spain international - he is his country's record goalscorer - scaled the La Mola mountain near Barcelona yesterday and reiterated his belief that he will be back before the end of the season.
Villa has targeted the Champions League final, should Barca overcome Chelsea in the last four, in Munich for his comeback with a view to earning a place in the Spain squad for Euro 2012.
"The leg is getting better all the time," Villa wrote on his Twitter feed.
"We are in line with the timetable set out."
