Apparently I won a signed Ruud Gullit shirt?

[harveyjoneys_NL]

So I was messaged (in Dutch, because I'm dutch) by a manager called Jesper Nagelsmann who said that I won the Invincible League challenge and thereby won the Ruud Gullit shirt. In order to send me this, he needs my address. But I don't want to give my address without knowing this isn't a scam. Is there a way to check if this is legit? Is there also a way to know who won and check if I really won?

Thanks in advance!

Hi,

I will forward this. Normally Gamebasics would send an e-mail to the winner and not ask for this in a chat message.

@FC-Eddie_NL Hi, ik heb m'n mail gecheckt en er was inderdaad een mail over dit. Ik heb ook gelijk eentje teruggeschreven. Thanks voor je antwoord!

Yeah, after you didn't reply to the e-mail they decided to send you chat message on OSM hoping for a reply So everything is legit
