Borussia Dortmund powered back from a goal down to crush hosts Bayer Leverkusen 4-2 in the Bundesliga on Sunday, keeping alive their chance of a top-four finish going into the final matchday next week.

Dortmund have now won six of their last seven league games to climb up from 11th to fifth and are just a point behind fourth-placed Freiburg.

They disrupted Xabi Alonso's farewell performance at Bayer Leverkusen's home ground, and they led 4-1 in the second half before conceded a goal in stoppage-time.

The Spaniard announced on Friday that he will leave at the end of the season, having joined in October 2022 and led them to the domestic double last season without defeat while also reaching the Europa League final.

"We played a very good first half but keeper [Dortmund keeper Gregor] Kobel made saves. In the second half, we were not good. But football today for me was not the most important thing."

A half-dozen saves by Dortmund keeper Gregor Kobel kept them in the game in the first half but after Leverkusen's goal the visitors never looked back.

Dortmund host relegated Holstein Kiel next week. Leverkusen's opponent next week is Mainz.

Bayern Munich on Saturday celebrated the league title they had secured a week earlier, beating Borussia Monchengladbach 2-0.
