The Catalan outfit have been favourites to carry the trophy on the Benito Villamarín Stadium on Saturday evening.
However targets from Kevin Gameiro and Rodrigo meant Lionel Messi’s late objective was merely a comfort and gave Valencia a historic victory.
Barcelona have been on the cusp of a treble this time final month – however a capitulation by the hands of Liverpool, adopted by tonight’s defeat, means the La Liga title is Valverde’s solely silverware this season.
“Barcelona looks psychologically broken, empty, soulless. How the hell didn’t the leadership inside the club didn’t notice it!? Valverde should’ve been sacked at Anfield and Pimienta managed the remaining matches,” one tweeted.
“I love to laugh and tonight it’s really easy to laugh. VALVERDE OUT,” one said.
“This better result in Valverde leaving or else,” one wrote.
“Valverde needs to leave at FT or next season could be much worse than this,” another said.
