The result marked Dortmund's fifth runners-up finish in the last eight Bundesliga seasons and pushed them beyond the 70-point mark for only the second time in the previous seven campaigns.

Frankfurt, managed by Albert Riera, made a blistering start and struck after just two minutes. Mahmoud Dahoud recovered possession near the edge of the area before feeding Can Uzun, who curled a precise finish into the far bottom corner.

It was the 30th Bundesliga game in 33 this season in which Frankfurt had scored, and the early breakthrough briefly lifted them above Freiburg into seventh place.

Dortmund responded after wasting several opportunities, with Marcel Sabitzer and Samuele Inacio both failing to convert promising chances.

The equaliser finally arrived late in the first half when Julian Ryerson drilled a low cross into the area and Serhou Guirassy guided a near-post finish into Michael Zetterer's top corner.

The hosts completed the turnaround in first-half stoppage time as Maximilian Beier set up Nico Schlotterbeck, who fired low inside the far post.

Frankfurt improved after the interval and thought they had levelled through Fares Chaibi, only for the goal to be ruled out for offside.

Instead, Dortmund extended their lead when Beier produced another assist for Inacio, whose close-range strike - his first goal for the club - was described as symbolic of a potential new era at Dortmund.

The match also marked Julian Brandt's final appearance at the Westfalenstadion as a Dortmund player.

Ansgar Knauff later assisted substitute Jonathan Burkardt for Frankfurt's second goal, but the visitors could not find an equaliser.

Their hopes of qualifying for the UEFA Conference League now depend on Freiburg's result on Sunday, with a Freiburg victory set to leave Frankfurt without major European football for a sixth consecutive season.

"We saw a very good finish to this last home game with a nice and deserved victory," said Dortmund head coach Niko Kovac.

"We were caught cold right at the beginning, but had the game under control after 15 minutes, and also scored the goals before half-time, which was of course very important. The second half was an open game from both teams.

"The way the team has acted, I liked it except for the first 15 minutes, and that's why I'm also happy that we finished the season in second place. You can be very happy with 70 points."
