Marcus Rashford and Ferran Torres scored the goals for the Catalans, who celebrated at Camp Nou.
El Clásico ended in a fiesta!
Barcelona beat Real Madrid and were crowned Spanish champions against their great rivals, who were without Kylian Mbappe.
Marcus Rashford opened the scoring in the 9th minute with a stunning free-kick, and Ferrán Torres extended the lead in the 18th minute with a great team move, following a superb assist from Dani Olmo.
Barça, with João Cancelo playing the full 90 minutes, established early on what would be the final result in a game marked by some heated exchanges.
The great duel of Spanish football ended in celebration for the Catalans, after beginning with a minute of silence in respect for Hansi Flick, the German coach who is mourning the death of his father this Sunday.
It is the 29th Spanish League title for the cules, who celebrated on the pitch and in the stands of Camp Nou, to the sound of Cant del Barca, the first conquest of a title in an El Clasico, a feat achieved only once before, by the merengues, in 1932. The match was marked by the expulsions of Javi Lopez in the 54th minute and Kwasi Sibo in the 78th, leaving Oviedo with a numerical disadvantage. Despite their resistance, the score remained 0-0 and almost sealed the fate of the Asturian team, who are in 20th and last place with 39 points, and can only be saved by a highly improbable combination of results.
