Pärnu Vaprus got promoted and was therefore replaced by the relegated Tallinna Kalev, who ended their three-year run in the top division.

[4] Before the season had started, multiple former Meistriliiga or the Estonian national team players joined a team in Esiliiga: Dmitri Kruglov[7] and Roman Sobtšenko[8] signed contracts with Maardu Linnameeskond, Ats Purje[9] returned from abroad to reach an agreement with Tallinna Kalev and Taavi Rähn[10] along with Toomas Tohver[11] joined Pärnu JK's staff.

On 7 April it was decided that the table will be split into two halves after the 27th round - six teams will fight for promotion and four will try to escape from relegation.

Firstly, Elva were forced to sack their chief executive Marek Naaris after it was revealed that he had been in contact with underage women.

Three teams got relegated after the last season: Rakvere Tarvas, Keila and Võru Helios will all play in II liiga after respectively ten, four and two years.

Before the 28th round, when the table was split into two, Tallinna Kalev U21 made a powerful recovery by winning five games in a row with a goal difference of 27:7 and was therefore handed a place in the top six.

Group A (North & East) In comparison to the previous season, only four teams got promoted or relegated: while Tallinn and Tallinna Legion U21 got promoted to Esiliiga B for the first time, Tartu Tammeka III and Jõgeva Wolves returned to the lower divisions after respectively three and two years in II liiga.

Whereas 2020 season's last and third to last team - Pärnu Poseidon and Põhja-Sakala - got relegated, the 13th placed Kose got readmitted for the second year in a row.

Hiiu County will have a team (Hiiumaa) in the fourth division for the first time since 2013 and Rummu Dünamo returns to the league after spending four years in III liiga.

The 2021 Women's higher division had only one team change in comparison to the previous year: the relegated Nõmme Kalju - who later decided against competing in the league system completely due to the scandal with their coach Getulio Aurelio[21] - was replaced by Esiliiga champion Tallinna Ajax & Paide Linnanaiskond joint team, who at the start of the season changed their name to Lasnamäe FC Ajax.

The title was decided on 6 November, when FC Flora beat their rivals 2:1 and was crowned as champions for the fourth season in a row,[23] meanwhile Saku finished second for the first time in their history.

At the same time, the relegation battle was not as intense: newcomer Lasnamäe Ajax got their first point in the 14th round, when they drew with Tartu Tammeka.

[17] 2021 Women's second division has three participant less than the previous season: Lasnamäe Ajax (got promoted), Tallinna Legion, Tartu Tammeka II, Kohtla-Järve Järve all lost their place in Esiliiga.

Seven teams remained the same as the previous year, the only change coming from Esiliiga's second-placed Rummu Dünamo getting promoted and replacing Sillamäe Alexela, who did not enter the league system.

Narva United spent most of the season in second place and finally reached play-off semifinals for the second time in successive years.

Third place belonged to Tartu's Ravens Futsal Ares Security, who finished in the top three for the first time in their history.

The team's start to the season was abysmal, picking up only two wins in their first eight matches, but getting 18 points from last six games raised them higher in the table.

Play-off: Relegation play-off: Due to the COVID-19 pandemic Esiliiga could not be finished and therefore the Estonian FA decided that the following year's Coolbet Saaliliiga will be contested between ten teams: all eight clubs in 2021 Coolbet Saaliliiga remain (Rummu Dünamo will not get relegated) and in addition two of the best Esiliiga team's also join.

Because the teams in the second division did not play the same number of games, it was decided that a small tournament - to determine the promoted sides - will be held in May 2021.

Due to the teams having played an uneven number of games, it was decided that the following year's top division will have ten clubs instead of eight.

While Sillamäe Kalev, Rõuge Saunamaa and Aruküla Radius took part in the tournament, Kadrina Vitamin Well declined from it.

Originally Narva Ganza, who was placed last in Esiliiga, was relegated into Teine liiga, but due to Sillamäe Dina not competing in the league system, they were readmitted to the second tier.

[27] The season was cancelled on 9 February, because of the strict COVID-19 rules in Estonia, which allowed only Meistriliiga's and Esiliiga's teams play.
