After leading Benfica to their sixth European Cup Final, Toni remained in charge of the team. He lost Rui Águas and Dito to Porto in a controversial case known as "Ademir affair"; but new signings such as Valdo Filho, Vata, Ricardo Gomes, and Ademir Alcântara helped guide the team to the 28th league title. Despite several draws in the first half of the season, and two losses between both halves, Benfica was much more regular. Several consecutive wins opened a six-point lead over Porto, with the title arriving on 7 May. Benfica also contested the 1989 Taça de Portugal Final, but lost it to Belenenses.
