input

"Here comes a perfectly valid argument: First of all, being an ex-fan of Villarreal CF is necessary for being a member of SK Rapid Wien. Next, some supporter of Östersunds FK is not an ex-fan of Villarreal CF. It follows that somebody is a supporter of Östersunds FK and not a member of SK Rapid Wien."
Is the argument, given the explicitly stated premises, deductively valid or invalid?
Options:
- valid 
- invalid
