Japan midfielder Shinji Kagawa scored his first competitive goal of the season and also set up the winner as Borussia Dortmund pulled off an extraordinary comeback to beat Norway's Odd 4-3 away in the first leg of their Europa League playoff qualifier on Thursday.

But Pierre-Emerick Aubameyang prodded home to start the comeback on 34 minutes. Kagawa then volleyed Marcel Schmelzer's cross into the bottom left-corner two minutes into the second half before a sensational second from Aubameyang made it 3-3.

Dortmund hit the woodwork yet again before Kagawa's cross found Henrikh Mkhitaryan to head home and complete the turnaround.

Takumi Minamino was substituted in the 74th minute of Salzburg's 2-0 defeat away to Belarusian club Dinamo Minsk, while Atomu Tanaka lasted just 23 minutes before being taken off in HJK Helsinki's thumping 5-1 defeat away to Russia's Krasnodar.
