Karim Benzema missed a penalty for Real Madrid as they finally blinked in the La Liga title race, dropping their first points of the season in a 1-1 draw with Osasuna on Sunday.

Elsewhere, Real Sociedad won 5-3 at Girona, and high-flying Real Betis fell to a 1-0 defeat at Celta Vigo.

After Barcelona beat Real Mallorca on Saturday, Madrid knew they had to win to stay top but were frustrated by Jagoba Arrasate's well-organized side at the Santiago Bernabeu.

Benzema, on his return to the side after injury, won a spot-kick but then fired it against the crossbar and also had a goal disallowed for offside as Madrid tried to force a way through.

Vinicius Junior broke the deadlock just before halftime with a cross that snuck all the way into the far corner, but Kike Garcia's well-taken header early in the second period earned Osasuna a point.

"What we were missing was scoring that penalty; normally, Karim scores them," Madrid coach Carlo Ancelotti told DAZN.

"He had no problem playing the 90 minutes. It's been a month since he's played; he has to get his best form back. He did his part; he had the chance from the penalty. It's an accident; sometimes it happens."

Real Madrid president Florentino Perez told the club's fans at an assembly on Sunday morning that a European Super League project was essential, but Osasuna showed domestic football can still offer a significant challenge.

The draw means Barcelona lead Madrid on goal difference after seven games, with both teams on 19 points and unbeaten. It is the first time the Catalans lead the league at the end of a fixture round since June 2020.

"We have to celebrate, they had won all their games, and we came back from a goal down; the team did great work and played a great game," said Arrasate.

Elsewhere, Juventus swept aside Bologna 3-0 to ease their recent troubles as Atalanta continued their dream start to the Serie A season with a 1-0 win over Fiorentina, which kept them level on points with leaders Napoli.

A routine third league win of the season against dismal opposition will stave off questions about coach Massimiliano Allegri's future until at least next weekend when they travel to champions AC Milan.

They are seventh, seven points behind the leading duo of Napoli and Atalanta, thanks to Filip Kostic's first goal for the club midway through the first half and two more after the break from strike pairing Dusan Vlahovic and Arkadiusz Milik.

"We hadn't won a game for a month; when we got back to the dressing room, we almost couldn't believe it," said Allegri. "We have to take it one step at a time; hopefully, we can close the gap like we did last season."

Before facing Milan, they host Maccabi Haifa on Wednesday, with a win over the Israelis essential for their hopes of reaching the Champions League's knockout rounds.
