While Villarreal finished last season in fifth place in La Liga, Huesca battled their way to the league title in the Segunda Division.
While Unai Emery received criticism for his time at Paris Saint-Germain and Arsenal respectively, there is a feeling that linking up with Villarreal has come at the right time.
Although he is under pressure to build on a productive campaign under Javier Calleja, Emery will be confident of eventually emulating the success that he had at Sevilla between 2013 and 2016.
With three home fixtures against lower-league opposition and a trip to troubled Barcelona to come in their opening four fixtures, Villarreal arguably have the ideal start to the campaign.
Nevertheless, failure to make the most of those games would put Emery on the back foot, particularly with a visit to Atletico Madrid also on the horizon.
The departures of Andre-Frank Zambo Anguissa and Santi Cazorla are big blows, but Villarreal will be delighted to have welcomed Francis Coquelin, Dani Parejo and Takefusa Kubo to the Yellow Submarine.
In the case of Huesca, they will be hoping to enjoy just their second-ever season in La Liga, rather than repeat their efforts from 2018-19 where they won just seven times.
However, having somehow managed to earn promotion despite suffering 14 defeats from 42 games at the second tier, they should be better prepared for their next experience among Spain's elite.
A considerable portion of their squad is made up of loan players, a group which includes former Wolverhampton Wanderers number nine Rafa Mir.
The main responsibility could fall onto the experienced shoulders of former Leicester City man Shinji Okazaki, who netted 12 times last season.

Debuts could be handed to Parejo and Kubo, although Coquelin may have to make do with a spot among the replacements.
Barring any late fitness issues, central defender Pablo Insua is Huesca's only fitness concern.
Having joined on loan earlier this week, former Manchester City defender Pablo Maffeo could line up at right-back.
Villarreal possible starting lineup:
Asenjo; Pena, Albiol, Torres, Pedraza; Chukwueze, Iborra, Parejo, Kubo; Alcacer, Moreno
Huesca possible starting lineup:
Fernandez; Maffeo, Pulido, Insua, Luisinho; Rico, Mosquera; Mir, Real, Ferreiro; Okazaki
We say: Villarreal 3-0 Huesca
Although Huesca will be motivated to make an impression on their return to the top flight, we feel that they could be overpowered by their hosts. Emery will be focused on claiming a top-four spot at the end of the season, and it would have been drilled into his squad that they must win games such as this one with minimal fuss.
