BARCELONA, Spain (AP) — Barcelona's title defense took a blow when it stumbled to a 1-0 defeat at Valladolid, missing the chance to move top of the Spanish standings on Saturday ahead of its Champions League clash with Manchester City at Camp Nou.
Atletico Madrid took advantage of Barcelona's latest slip by winning 2-0 at Celta Vigo courtesy of David Villa's two goals in a three-minute span to move ahead of Barcelona and level on points with Real Madrid at the top of the standings.
Once the league pacesetter, Barcelona has won just two of its last seven away league games and trails its title rivals by one point before Madrid hosts Levante on Sunday.
Lionel Messi was the only Barcelona player who looked sharp, while his teammates were plagued by uncharacteristic passing errors and again proved brittle at the back.
Valladolid outplayed the defending champions early and midfielder Fausto Rossi netted the winner in the 17th minute. The relegation-threatened side then did well to protect three points against the star-studded visitors for the remainder.
After its strong start this season under first-year coach Gerardo Martino, Barcelona has dropped points in five of the last nine rounds.
"As long as it is mathematically possible we will keep fighting," said Martino, whose team visits Madrid in two weeks. "We are not in our best form, and we have to rediscover it within 15 days. We are worried because the league title is being decided right now."
Before the clasico, however, Martino will have to regroup his team against City on Wednesday. Barcelona will be looking to protect its 2-0 lead in the second leg of their Champions League last-16 tie.
Valladolid started the round in the drop zone, but the big win — only its fifth in 27 rounds — provisionally pulled it out of danger.
"It's an incredible result," said Rossi, who was at Valladolid on loan from Juventus. "All together we can save this team."
Also, last-place Real Betis gave a boost to its slim hopes of staying up by beating Getafe 2-0 in Seville, while Villarreal lost 2-0 at Granada to falter in the race for fourth place.
After Barcelona lost 3-1 at Real Sociedad in its last league away match, Martino aligned his best 11 available without Andres Iniesta, who didn't travel with the team for undisclosed personal reasons.
