Xavi's side could not end the campaign with a win against a Celta side who secured survival
Barcelona's season ended with a 2-1 defeat at Celta Vigo, who secured their place in LaLiga next season with the win.
Gabri Veiga scored both goals for Celta, with Barca's consolation coming from Ansu Fati late on.
Barca end the campaign as champions regardless for the first time since 2019, finishing 10 points clear of Real Madrid, while Celta climb to 13th having begun the weekend in danger of relegation.
Xavi Hernandez made changes with Ronald Araujo, Pedri and Alejandro Balde all injured, while Sergio Busquets and Jordi Alba played their last games for the club last weekend.
One of those to come into the side, Franck Kessie, thought he had opened the scoring in the first half, but VAR revealed he was just offside when he received Robert Lewandowski's pass.
Veiga did break the deadlock before the break, the teenager netting his 10th goal of the season from midfield with a smart finish.
It meant Marc-Andre ter Stegen missed out on the LaLiga clean sheet record, ending the campaign with 26 shut outs and, therefore, only matching the record.
With that record gone, Ter Stegen was withdrawn on the hour and his replacement, Inaki Pena, won't want to see Veiga's second goal, a cross which caught him out.
Substitute Ansu scored this third goal in two games to get Barca back into the match late on, but there was to be no late leveller as Celta held on to spark wild celebrations in Vigo as they stayed up on the final day.
