Lamine Yamal needed less than a minute to make an impact in his return to action after an injury.

Yamal came off the bench in the second half and set up Robert Lewandowski's 59th-minute go-ahead goal in Barcelona's 2-1 win against Real Sociedad in the Spanish league on Sunday.

The fifth win in a row for the Catalan club across all competitions moved Barcelona to the top of the Spanish league, one point ahead of Real Madrid, which was crushed 5-2 by Atletico Madrid on Saturday.

Yamal came into the match in the 58th to replace Roony Bardghji and make his first appearance after missing four matches because of a pubic-area injury sustained while playing for Spain's national team during the international break.

Yamal also had a goal disallowed for offside in the 74th, and nearly set up another Lewandowski goal in the 84th, when the Poland striker was denied by the crossbar.

Before the match, Yamal presented to fans his Ballon d'Or award for best young player of the year.

Barcelona still doesn't have the right permits to return to the renovated Camp Nou Stadium. It was back at Montjuic stadium after playing its first two home matches in the Spanish league in a 6,000-capacity venue at its training facility.

The club will also host Paris Saint-Germain at the Montjuic on Wednesday in its home opener in the league phase of the Champions League.

Sociedad opened the scoring with a close-range shot by Álvaro Odriozola following a breakaway in the 31st in what was Sociedad's only attempt on target in the first half. Jules Koundé equalized for Barcelona with a header off a corner kick in the 43rd.

Sociedad midfielder Takefusa Kubo hit the post in the 72nd and 84th minutes.

Barcelona coach Hansi Flick opted for the debut of 17-year-old Pedro "Dro" Fernández, who started in midfield.

It was the fourth loss in five matches for Sociedad. The Basque Country club was coming off a 1-0 win over Mallorca in what was its first victory of the season.
