Hello, I'm Mattythewhite. I noticed that you added or changed content in an article, Robert Prosinečki, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. If you need guidance on referencing, please see the referencing for beginners tutorial, or if you think I made a mistake, you can leave me a message on my talk page. Thank you.

Infobox timestamps
Hello, I'm Mattythewhite. Welcome to Wikipedia! I just wanted to let you know that one or more of your recent contributions were not quite right. When updating statistics within the infobox of a footballer, please make sure you update the timestamp at the same time, so that both readers and fellow editors know when the information was last updated.

You can do this by replacing the existing timestamp within the club-update or pcupdate parameter for club stats, or the nationalteam-update or ntupdate parameter for international stats. For articles that use a DMY date format, use five tildes, or for MDY dates, use mdytime. This will generate the specific time the update was made.

If you have any questions about this, feel free to leave me a message on my talk page. Thank you, Mattythewhite (talk) 12:17, 9 July 2019 (UTC)
