[3] Valladolid's honours include a single trophy of great relevance, the defunct Copa de la Liga 1983–84.

Two of its players have won the Pichichi Trophy: Manuel Badenes and Jorge da Silva; and ten were internationals with the Spain national football team.

On 3 September 2018, it was announced that Brazilian former international footballer Ronaldo Nazario had become the majority shareholder after purchasing a 51% controlling stake in the club.

The following year, the team pushed on from this success and reached the finals of the Copa del Rey in Chamartín Stadium against Athletic Bilbao, losing 4–1.

The next ten years were spent in the first division, and relegation was short-lived as Valladolid gained promotion again in 1958–59 with a 5–0 win over Terrassa under manager José Luis Saso,[7] a legendary figure in club history.

In the 2006–07 season, after signing Basque José Luis Mendilibar as head coach, Valladolid had one of its best years in its history while playing in the second level.

Also remarkable was the side's role in the season's Copa del Rey, reaching the quarter-finals after defeating two top division teams, Gimnàstic de Tarragona (4–1 aggregate) and the 2005–06 UEFA Champions League contender Villarreal (3–1), while playing the entire competition with reserve players.

The week following his sacking, Valladolid dropped into the relegation zone (something that never happened during Mendilibar's 138-match stint), with former player Onésimo Sánchez taking charge.

Former Spain national team manager Javier Clemente was named Sánchez's replacement in a desperate move to avoid relegation with only eight matches remaining.

After a brief breather (16th position), Valladolid again returned to the bottom three, then faced a must-win last game at the Camp Nou against a Barcelona squad needing a win to secure the Liga championship.

Level in the standings with Racing de Santander, Málaga and Tenerife for the two final safe positions, Valladolid lost 0–4 and consequently was relegated, ending a three-year stay in the top flight.

The 2011–12 season saw Valladolid return to La Liga under the management of Miroslav Đukić, promoted through the play-offs after finishing third in the division.

[9] In the 2017–18 season, Valladolid was promoted back to first division after four years via play-off defeating Sporting de Gijón and Numancia.

[10][11] This process concluded with the acquisition led by the former Brazilian player Ronaldo Nazário, who was officially introduced as the majority shareholder and president of the board of directors on 3 September 2018.

[15] Their standing improved to 6th place by the 10th round, but a lack of goals combined with a deteriorating defense resulted in a series of unfavorable outcomes.

However, the team's performance notably picked up in the final rounds of the season, ensuring their safety in the league mathematically one match prior to the end of the championship.

[19] In January, Ronaldo signed high-profile player Ben Arfa, who played sparingly and left at the season's end.

[20] On 10 July 2020, members of Atlético Tordesillas agreed to have the team become a subsidiary of Real Valladolid for one season, extendable over time.

The preferred option was the Estadio Nueva Balastera in Palencia, provided it met the minimum requirements set by the LFP.

They needed to beat the league champions, Atlético de Madrid, and hope their rivals didn't win their matches.

Despite various challenges including injuries and COVID-19 absences, coach Sergio González Soriano remained in charge throughout the season, ultimately leading the team back to the lower division.

It is important to note that the earlier record was set in La Liga by César Sánchez, who went 555 minutes without conceding a goal.

The season was marked by inconsistent performance, swinging between periods of positive and negative results, often conceding goals in the closing minutes of matches.

[35] Real Valladolid play at the 26,421-capacity Estadio Nuevo José Zorrilla, finished in 1982 to replace the previous stadium of the same name which had stood since 1940(increased its capacity from 27,846).

After opening for the club on 20 February 1982, it hosted the Copa del Rey Final on 13 April of that year, and then three Group D matches at the 1982 FIFA World Cup.

This project was known as Valladolid Arena [baʎaˈðolið aˈɾena], but was contingent on Spain winning the right to host the 2018 FIFA World cup.

[45] The Promesas wore their previously mentioned kit without issue during their Segunda Federación match against Real Oviedo Vetusta last week.
