The last ticket to Spanish top flight in 2021/22 season was eventually grabbed by Rayo Vallecano. They managed to thump Girona 2-0 in the La Liga play off last weekend on the road. Alvaro Riviera anf the former Argentina international Oscar Trejo bagged their winning goals. They even held on till the final whistle after they were down to ten men due to the expulsion of Emiliano Velasquez. Such was a dramatic comeback since they were defeated 1-2 in their home turf at the first leg. This is their eighth promotion in the club's history.

Andoni Iraola's men were not exactly the favorite to bump up from the Segunda division as they only finished on the sixth in the final standings below Almeria, Leganes and Girona sitting from the third to the fifth respectively. Vallecano has gone through a number of misfortune throughout the season. It had a number of players tested positive COVID-19, injured and other off-the-pitch's issue such as the club's failure to compensate their fans' ticket in this world pandemic and inability to pay the players's delayed salary.

Rayo Vallecano's success to bounce back to La Liga after two years at the second tiers also means that Oscar Trejo and Co officially follows Espanyol and Real Mallorca sitting on the 1st and 2nd of the table. These two clubs which instantly made their return to the first tier after being relegated in 2019/2020 season, collected the same points, 82.

Espanyol, guided by Vicente Moreno, still counts on most of the players from last season such as Raul de Tomas, David Lopez, Wu Lei, Mathias Vargas and the veteran goalkeeper Diego Lopez. They sealed the promotion ticket the earliest. The runner up Mallorca is currently under the command of Raul Garcia, the former boss of Levante, Getafe and Villareal. Their notable figures in the squad last season were Abdon Prats, Salva Sevilla, Lago Junior and Amath Diaye.

Espanyol's most notable honors were while winning Copa Del Rey fourth times plus being the UEFA Cup finalist twice, in 1988 and 2007. Meanwhile, RCD Mallorca's best campaign was in 2002/03 when they won their first Copa Del Rey, and in 1998/99 when they were able to reach UEFA Winners Cup final before being beaten by Lazio.
