Yup, I was pretty sure you wanted a repeating group, but I thought what I gave you might help you get there.
For a repeating group, you could set the type of content to User and set the data source to Search for Matches:each item's goal scorers:unique elements. Then, have a text element in the repeating group that displays the current cell’s user’s name, and finally, while I don’t love doing searches within elements in repeating groups, have another text element that has the expression I showed in my screenshots minus the constraint on the search for matches and changing Current User in the advanced filter to Current cell's User.
Anyway, that’s one way to go, and I will see myself out of this thread now. Best of luck!
