Udinese took their surprising 2-0 lead from the first leg at the Westfalenstadion back home and Dortmund started the match with plenty of work to do.
Before kick both Pasquale Marino and Jurgen Klopp had said that Udinese would not find it so easy this time around and both were indeed justified.
Both squads started with a majority of their first team players as Udinese looked to secure their aggregate lead and Borussia Dortmund knew they would need a monumental result to overturn it.
The Zebrette started with a fairly offensive line-up with the in-form trident of Antonio DiNatale, Simone Pepe, and Antonio Floro Flores in the attack.
At times, Swiss forward Alexander Frei found himself isolated toiling upfront on his own, but he still managed to put the ball in the net, however the referee called it back for a close offside decision.
It was still Dortmund who took the lead through midfielder Tamas Hanjal on 45 minutes.
The first half was extremely entertaining with the play moving back and forth at a quick pace. The second half also started off with plenty of thrills for the supporters as Di Natale and Frei again exchanged two goals over-ruled for offside.
Udinese were beginning to defend in numbers and both teams were giving their all as the result hung in the balance. However, the German giants continued to press and just as Udinese must’ve been starting their celebrations Borussia Dortmund amazingly scored again.
Hanjal saved his side from going out of the competition as he made it 2-0 in the final minute following some chaotic play in the Udinese box to force extra-time. The thirty minutes of extra time ended the same way they began so the match went into the inevitable penalty shoot-out.
The Penalties began with Maurizio Domizzi and Tamas Hanjal missing their kicks. However, Udinese were perfect for the rest of the shootout and Dortmund's Jakub Blaszczykowski missed a decisive penalty. So the Bianconeri advance to the next round of the competition.
The group stage draw will be made next Tuesday. The 40 teams which went through tonigh will be put into eight groups of five.
