Barca were denied the opener at The Mestalla as Lionel Messi’s tame shot after half an hour was spilt by goalkeeper Neto and bounced over the line before the Brazilian dragged it back over but referee Ignacio Iglesias Villanueva allowed play to continue.
The Argentine forward and his team mates remonstrated with the officials to no avail but still had a big say in the game, laying on a perfect pass for Alba’s 82nd minute leveller, reports Reuters.
Spain striker Rodrigo Moreno put host Valencia ahead on the hour, sneaking ahead of Barca defender Thomas Vermaelen to score from close range before putting on an orange wig in tribute to the club’s late president Jaume Orti who passed away on Friday.
Barcelona lead the standings on 35 points, Valencia have 31 while Atletico Madrid are third on 27, level on points with fourth-placed champions Real Madrid.
“It was a good game and it was defined by a controversial play but we know Valencia’s potential. We’re not satisfied with everything but we’ve managed to take something positive from the game,” Barca coach Ernesto Valverde said.
Valencia assistant coach Ruben Urria added: “We struggled at first because Barcelona are a great team and came here to win against the second best team in the league.”
“Everything changed in the second half and we were the better team. These players are making history.”
Before kick off, Valencia paid tribute to Orti, president during the club’s last two Liga title-winning seasons in 2002 and 2004, and an electric atmosphere gripped The Mestalla.
