During the summer, midfielder Simon Olsson left Elfsborgs for Dutch SC Heerenveen.
From his shadow, Michael Baidoo has emerged as the Borås team's currently most in-form goalscorer.
Because just like against Malmö last time, the 23-year-old struck twice again.
First, he beautifully sunk in the lead goal in the beginning of the match, assisted by Per Frick.
Later, Baidoo added on a penalty with his sixth goal of the season, after the same Frick was brought down in the box.
An important victory for Elfsborg, who after fourth place in the Allsvenskan last year have had a much tougher time this year and are parked in ninth place in the table.
Nevertheless, it is nothing compared to Sundsvall, which is in the jumbo place.
Today's loss was the team's ninth straight in the Allsvenskan.
