The young South Korea international has been a relevation at Augsburg, boosting their survival hopes, and he admits he\'s open to staying with the club.Augsburg\'s on-loan and in-form attacker Koo Ja-Cheol says he doesn\'t know where his future lay but is open to the possibility of a permanent move away from Wolfsburg.The 23-year-old South Korea international has been a revelation at struggling Augsburg since joining the club on loan from Wolfsburg in January.Koo, whose three goals and one assist have helped Augsburg move clear of the relegation zone, told Ilgan Sports he doesn\'t yet know where his future is despite being contracted with Wolfsburg.\"I will be able to know that after this season is done. I still have two years left in my contract with Wolfsburg. But I’m thinking about opening all the possibilities,\" he said.Koo has cemented himself as a key member of the Augsburg line-up since his move, while he struggled for regular first-team opportunities at Wolfsburg earlier in the season. He admitted he had been driven by his tough times at Wolfsburg to improve at Augsburg.\"The painful memories in Wolfsburg helped me a lot. I tried to focus on the field thinking about mistakes that I made with my former team,\" he said.\"In fact, the experience of playing both centre and sides in Wolfsburg helped me a lot. Right now, my fitness and confidence level is at 100 per cent.\"Koo admitted his short-term goal was to continue his good form at Augsburg and keep the side in the Bundesliga.\"My goal in Augsburg was to get at least five offensive marks, but I achieved that faster than I expected. Now, I will help my club to remain in the top division,\" he said.\"I want to go to the Olympics and the World Cup after showing a good performance with my club.\"On the 2012 London Olympics, he added: \"I hope that I can play on both the Olympic team and the senior national team.\"I have a good relationship with the Olympic team, where former team-mates from the U-20 national team are now core members. My heart and body is waiting for the Olympics. I’m trying hard to fulfill that dream.\"Meanwhile, he\'s also excited about the national team\'s World Cup hopes as well as the scheduled May friendly against world and European champions Spain.\"There is always something to learn against strong sides. I think we can build up confidence and competitiveness,\" he said.\"Since I’ve been playing in Europe, my fear of European teams has diminished. If I get the call from the national team, it will be a very fun time for me.\"
