In the 2020 season, FC Gais played in the Superettan under the leadership of head coach Stefan Jacobsson. The first half of the season went hard for the team, which had a hard time scoring points. The second half, however, became much more productive and they made a strong effort as a team. The addition of Adnan Maric to the team and the change of game idea in the middle of the season was a clear factor in why Gais ended the season so strongly. Gais Fotboll finished the season in tenth place, which meant that the team got to play in the Superettan also in the 2021 season.
According to f.d. chairman Jonas Andersson, FC Gais had a good pre-season ahead of the 2021 season, and the team started the series well with two wins and a draw, but the season ended in failure. The team ended up in the qualifiers and then lost the relegation qualifier against Dalkurd FF, which means that the team plays in Ettan Södra season 2022. Jonas Andersson and Tony Balogh (vice chairman of the Mackerel) believe that it was a mixture of mistakes and bad luck that was behind the relegation. They point out that midfielder Aiham Ousou was sold after eleven games and that goal scorer Richard Yarsuvat broke his foot and that Adnan Maric could only play just under half of all matches due to injuries. After the relegation, Jonas Andersson and Jonas Östergaard resigned, something that the supporters had demanded several times during the season.
The 2022 season was expected to be financially tough for the association, as the board already during a members’ meeting in December 2021 announced that it expected sales to be halved. The 2022 season, however, started sportingly well; after 14 rounds played, GAIS FC led the series when the series entered the summer break. In addition, GAIS won the match against Lindome GIF on 28 June in the Swedish Cup’s first qualifying round.
