Atletico Madrid have been held by Celta Vigo to a 0-0 draw at home on, missing their chance to regain the Spanish La Liga lead.
A victory would have seen Atletico replace Sevilla at the top, but the hosts failed to capitalise on their chances at the Wanda Metropolitano Stadium.
Atletico has the same 10 points as Sevilla but trail on goal difference.
Sevilla have a game in hand.
It was the third winless match in a row for Atletico, who were coming off a 2-2 home draw against Juventus in the European Champions League.
Last weekend, Diego Simeone's team lost 2-0 at Real Sociedad in their first setback of the season.
"We tried every way possible," Atletico defender Jose Maria Gimenez said.
"We went for the win until the last minute. It wasn't easy but we kept fighting. At least we didn't concede this time, but we let two important points slip away."
Atletico have conceded six goals in their last three matches.
Atletico striker Diego Costa and Celta defender Lucas Olaza were shown yellow cards after the final whistle as players from both teams got into an altercation.
Celta, who were coming off a home loss against Granada, stayed 14th in the 20-team standings with five points from five matches.
They hadn't won a point at Atletico since 2014.
Atletico visit Mallorca on Wednesday, while Celta host Espanyol on Thursday.
Earlier on Saturday, Villarreal defeated Valladolid at home with two late goals, while Levante were held by visiting Eibar to a 0-0 draw.
Villarreal moved to third place with their second straight victory.
Barcelona visit Granada later on Saturday in what is set to be Lionel Messi's first league appearance after a long injury absence. Barcelona have only seven points from their first four matches.
On Sunday, fourth-place Real Madrid visit Sevilla, where they have lost four straight league games.
