Context for 2020–2021

• Botafogo experienced a turbulent period across the 2020/21 window. In the 2020 Campeonato Brasileiro (season played during that calendar year) the club was relegated from Série A and therefore competed in Série B in 2021.
• The club also took part in the regional Campeonato Carioca (state championship) and the Copa do Brasil during this period.
• Following relegation there was significant squad turnover and managerial changes as the club reorganized to mount a promotion campaign.

Coach: Flávio Tênis (Flávio Tenius)

• Flávio Tênis is a long-serving member of Botafogo's coaching structure, known for work with the club's youth and as an assistant. Around 2020/21 he acted as an interim/head coach on occasions when the club changed managers.
• As interim coach he typically stabilized the team, worked with available first-team players, and tried to integrate younger players from the club’s academy during transitional periods.

Practical notes about the era

• The relegation in 2020 triggered an extensive rebuild: many players left and the squad for Série B (2021) looked different from the 2020 Série A roster.
• Botafogo’s objectives in 2021 focused on regaining top-flight status and re-establishing financial and sporting stability.
• For match-by-match results, full squad lists and exact dates of coaching spells, consult specialized databases (club site, Transfermarkt, Soccerway) or official federation records for precise, game-level detail.

Summary

Around the 2020/21 period Botafogo was a historic Rio club navigating relegation and rebuilding. Flávio Tênis served as a trusted interim/assistant figure in the coaching setup during transitions, providing continuity while the club sought longer-term solutions and prepared for the Série B campaign.
