Hi, I am currently working on a scientific paper that deals with the application of a new ranking algorithm. In order to test this ranking, i decided to make a ranking that identifies the best player on the field. Therefore, i am looking for the correct translation for the german word "Zweikampfstärke" or "Zweikampf". I guess there is a soccer specific expression for it. Dictionaries translate it with "duel", but i don't think that that's the correct word. Thanks.
