Who is Sean Lynch and what exactly is he doing in Croatia’s World Cup squad?

This is going to get curiouser and curiouser...

JOE reader John Nolan was looking through the World Cup squads on the ESPN mobile site when he came across the kind of name you wouldn't normally associate with the Croatian national football team. In among the Nikica Jelavics, Niko Kranjcars and Luka Modrics of this world sat the most Irish name you could possibly come up with. Just after the name of Inter Milan wunderkind Mateo Kovacic appears one Sean Lynch, who plays for HSV - a common abbreviation of German side Hamburg, except that no such player is associated with the Bundesliga outfit. He clearly doesn't exist, despite the fact that FOX Sports feature the exact same player in their list of Croatian players for Brazil. Sean Lynch, if you're out there, get in touch and tell us how the preparations are going. We'd also be very curious to know if you ever had an Irish granny.
