It was a squad everyone said was too good to go down. The repercussions would be too great for the club. But thanks to variety of pressures, the team did eventually go down on the final day.
Why exactly Villarreal crumbled is very hard to pinpoint. They started the season with the same manager that took them to the Champions League last season, Juan Carlos Garrido.
However, this season, he was unable to replicate his work of last season, guiding Villarreal through a terrible Champions League campaign while the team badly underperformed in La Liga as well.
When he was sacked, though, things only got worse. Jose Francisco Molina, another ex-Villarreal B coach, could not handle the pressurized situation he was stepping into, and could not bring about the immediate reversal of results needed at the club.
As a result, he too was sacked, and the club looked very desperate with their appointment of Miguel Angel Lotina, the man who saw Deportivo De La Coruna, one of Spain's historically biggest sides, get relegated last season.
Unsurprisingly, he wasn't the man to do the job for Villarreal either, and it was under him that Villarreal fell into the drop zone for the final time on Matchday 38, despite having stayed clear of the zone since Matchday 21.
The factors that played into Villarreal's relegation are many, and are best saved for a discussion at a later time. What needs to be discussed right now is this: What now for Villarreal's players?
Despite underachieving as a squad, Villarreal still possesses some incredibly talented players.
Diego Lopez, Mateo Musacchio, Rodriguez Gonzalo, Honorato Nilmar, Guiseppe Rossi, Borja Valero, Soriano Bruno and Cristian Zapata are all far too good to ply their trade in the second level of Spanish football.
Cani, Marco Ruben and Julian De Guzman are also better than your average La Liga player, so their status with Villarreal is rather uncertain.
I'd expect somewhere between six to 10 high-quality departures from Villarreal this summer, and I expect most of the players will look to remain in La Liga, since most of them have been playing in the league for the majority of their career.
Where they end up will really affect the balance of power in La Liga.
