I was approached by some of you with regards to testing data of goalkeepers (and field players). As some of you might know, there is not a lot of data on goalkeepers in the current literature.
Therefore I would like to offer different things.
Depending on the response there will be a timely post.
If there are any question with regards to the points above, and or if you would like to participate - I would be happy if you sent me an email to firstname.lastname@example.org
