Competing at the 2020 Russian Championships, Zahorski/Guerreiro placed third in the rhythm dance. Third in the free dance as well, they returned to the national podium as bronze medalists. Zahorski said "before this competition, we actually got in training. We had a good two and a half weeks of training, so hopefully, going into Europeans, we’ll add more and it will be much better." At the 2020 European Championships, they placed fourth in the fifth in the rhythm dance, but dropped to sixth place after the free dance. They had been assigned to compete at the World Championships in Montreal, but these were cancelled as a result of the COVID-19 pandemic.
