This was one of the best games in the world this year! We won three zero there, they won three zero here, a missed penalty in stoppage time - a crazy game, but great for Asian football. I am so tired, but so happy that we made it to the semi-finals.

Dejan Damjanovic shares his thoughts on Suwon Samsung Bluewings' rollercoaster quarter-finals tie with Jeonbuk Hyundai Motors, after the hosts came out on top 4-2 in a penalty shoot-out after a 3-3 aggregate draw.

It wouldn't have made for comfortable viewing for Suwon fans on the night, but despite the 3-0 defeat to Jeonbuk at Suwon World Cup Stadium that extinguished a three-goal lead from the first leg, their side were able to see out extra-time and triumph in the resulting penalty shootout.

The victory was thanks largely to the heroics of goalkeeper Shin who not only denied Adriano a match-winning penalty in stoppage time, but also saved from Kim Shin-wook and Lee Dong-gook in the shoot-out, as Suwon ultimately triumphed 4-2.
