Atletico's city neighbours Real turned in one of their best performances this term and Cristiano Ronaldo and Angel di Maria each scored twice as the champions crushed Valencia 5-0, although they are still 15 points behind arch rivals Barca in third with just over half the season played.
Barca crashed to their first reverse of the campaign when they let slip a two-goal lead and were beaten 3-2 at Sociedad on Saturday and Atletico maintained their perfect home record with an efficient performance against Valencia-based Levante.
Diego Simeone's resurgent side, whose latest victory was soured by an injury to top scorer Radamel Falcao, have won all 10 of their league matches at their Calderon stadium and are second on 47 points from 20 of 38 games.
Simeone said breaking records was all very well but he wanted his players to focus on Thursday's King's Cup quarter-final second leg at Real Betis, when Atletico will be protecting a 2-0 lead from Thursday's first leg.
"The statistics are important but we won't spend time looking at them," the Argentine told a news conference.
"Now we have a very tough game [against Betis] in Seville and the only thing we must focus on is that game."
Colombia striker Falcao, who is coveted by several of Europe's richest clubs, pulled up early in the second half clutching the back of his left leg and had to be replaced by Diego Costa.
"He will rest and he will be in very good shape further down the line," Simeone said.
Jose Mourinho's Real side romped to a second victory of the week against Valencia after Tuesday's 2-0 Cup quarter-final first leg success at the Bernabeu and they return to the Mestalla for the second leg on Wednesday.
They will be on a high after tearing Valencia apart in the first half of Sunday's league game with a brilliant display of counter-attacking football that brought back memories of their superb form in winning the title last season.
