Barcelona –

Barcelona claimed its 27th La Liga title and its first in four years after two first-half goals from Robert Lewandowski sparked a comfortable 4-2 victory over Espanyol on Sunday.

Barca moved to 85 points from 34 matches and extended its lead at the summit to an unassailable 14 points over second-placed Real Madrid.

There was little time for jubilation, however, as the visitors had to quickly rush off the pitch after the match as several Espanyol fans invaded the field as Barca started to celebrate the title.

The Barcelona players will have to wait until Saturday to lift the league trophy. Barcelona will host fourth-placed Real Sociedad in front of its jubilant fans, who will pack Camp Nou.

It will no doubt be an emotional occasion for captain Sergio Busquets, who announced last week that he will be leaving Barca at the end of the season after 15 years with the club.

Busquets has won nine league titles and 32 overall with the club. He has won three Champions League titles, seven in the Copa del Rey and three FIFA Club World Cup in addition to winning the 2010 World Cup and 2012 European championship with Spain.

"I'm delighted, I think we had a spectacular campaign and clinched it today with a great win," Busquets said.

"We are a solid team, a well-oiled squad with an outstanding defense and that's how champions are built.

"I'm proud of what we did the entire season, being solid and regular, winning the games we should and not dropping points. It was a remarkable season and I'm so happy to end my history here this way."

Barca was the superior side against lowly Espanyol, which is fighting to avoid relegation, and opened the scoring early with a close-range strike by Lewandowski.

Alejandro Balde scored Barca's second with a tap-in from a Pedri cross in the 20th minute.

Lewandowski extended the lead five minutes before the break with another close-range finish from a Raphinha cross.

Defender Jules Kounde headed in Barca's fourth in the 53rd minute, before Javi Puado and Joselu scored consolation goals for Espanyol.

Barcelona has won 27 of its 34 games this season, with the title charge built largely on its outstanding defense, which has conceded just13 goals, by far the best defensive record in Europe’s top five leagues.
