Slaven Belupo started the season with a batch of mixed results, drawing 5 out of their 7 opening games. Their first win came on 16 October 2020 on matchday 8, with a scoreline of 5:1 against Istra 1961.[1] Slaven Belupo stopped drawing games until the winter break, winning 4 out of 12 games.[2] After the winter break, Slaven Belupo yet again entered drawing form, drawing 8 out of 14 games. After that, they stopped drawing again and lost 5 games in a row, coming closer to the relegation zone.[3] Before the final matchday, Slaven Belupo were only 3 points above the relegation zone. Despiite the concerns, Slaven Belupo survived with a dramatic goal from Lovro Zvonarek, ensuring a 1:0 victory over relegation rivals NK Varaždin. Despite the survival and a 7th place finish, Tomislav Stipić was sacked on 10 June 2021 after just 2 wins after the winter break.[4]
