Valencia fans decided to protest against their ownership on Saturday by refusing to enter the stadium and the atmosphere outside was truly spectacular.
Jose Bordalas' side started the final matchweek of this La Liga season in the bottom half and it's been a miserable campaign overall.
Meriton Holdings, owned by Peter Lim, took over Valencia in 2014 and saved the Spanish giants from administration and they'd go on a solid run, even qualifying for the Champions League in 2017 and 2018.

A lot of that came under sporting director Mateu Alamany and manager Marcelino, but the pair were both sacked in 2019 and Valencia have slid down the table once again with a number of different managers at the helm.
Supporters have been demanding Lim to sell the club ever since and during their clash with Celta Vigo, they pulled their trump card.
Thousands showed up at the Mestalla with no intention of going inside to watch the football. Listen to that noise in the videos above. Absolutely huge.
The videos have quickly gone viral on social media and even rival fans are in awe.
One commented: "This is how you protest a clubs ownership, none of that s**t our fans do."
Another said: "Set the standard this."
A third tweeted: "No team in England would do this."
While someone put: "That's how to do it...."
Valencia would end up winning the game thanks to a Maxi Gomez strike in the first half and Nestor Araujo own goal on the hour mark.
They've moved up to ninth in the table and will stay there, unless Osasuna win against Real Mallorca on Sunday.
Things could go from bad to worse for Valencia in the summer, with Barcelona interested in left-back Jose Gaya and midfielder Carlos Soler.
It's believed Barcelona president Joan Laporta has already met with Valencia executives to discuss potential transfers.
The Blaugrana's bloated squad means they'd find it hard to register the Spanish duo, but they've tried to come up with a compromise.
Martin Braithwaite, Riqui Puig and Sergino Dest have been offered in exchange.
It's unlikely those players will interest Valencia however and negotiations are likely to continue.
