"Is Fred a fan of Liverpool? Are supporters of Real Madrid devotees of PSG? In European football, it is sometimes difficult to keep track of the mutual admiration and dislike. The following argument seeks to clarify some such relations: Every expert of Yeni Malatyaspor is not a friend of Wolverhampton Wanderers FC or not a fan of FC Arouca. Being a friend of Fenerbahçe SK is necessary for not being a friend of Wolverhampton Wanderers FC. Nobody is neither a fan of FC Arouca nor a friend of Fenerbahçe SK. From this follows: Being a friend of Fenerbahçe SK is necessary for being an expert of Yeni Malatyaspor."
Is the argument, given the explicitly stated premises, deductively valid or invalid?
Options:
- valid 
- invalid
