Former Copenhagen defender William Kvist does not know what he would do if he scored against his former club in the Europa League.
The Dane, who scored for his country against Italy in a recent World Cup qualifier, has yet to open his account for Stuttgart since joining the Bundesliga club just over a year ago and time may be ripe for that to change.
``I think if it were to happen, I would be so surprised that I would not know how I would celebrate,'' he said.
Kvist does know that he and his team-mates have to be celebrating at the final whistle, however.
``A club like Stuttgart must come through a group like this,'' he said.
``We now have to show that we are better than our position.''
Kvist spent 19 years with Copenhagen prior to his move to the Bundesliga in 2011, and he admits it ``will be a strange feeling'' to be on the opposition.
``I played my first game for Copenhagen at the age of eight,'' said the 27-year-old.
Stuttgart will be without Arthur Boka, who picked up a deep cut while denying Hamburg's Rafael van der Vaart a goal in a 1-0 win which has given the Swabians a boost.
``If we can carry the momentum out of the Hamburg game and perform like we did there again, then we can certainly pick up our first win in the group,'' said captain Serdar Tasci.
Copenhagen arrive at the Mercedes-Benz Arena in confident mood after a 1-0 win over city rivals Brondby, giving them a second derby victory this season and keep them top of the Danish Super League.
``It is always good to win a derby,'' said their coach Ariel Jacobs on the Danish club's website.
