Stéphane Lannoy is a French federation referee since 1998. Lannoy played football until he was 20, didn't think he was good enough to become a professional and turned to refereeing instead. Something he had been doing already, while playing.
First division referee from 2002, international ref from 2006. Lannoy was promoted to the UEFA elite category at the start of season 2009-2010.
Three matches in the U21 European Championships in the Netherlands, a qualifier for the UEFA Cup in 2006 and one in 2007, one EUFA Cup match in 2006 and then suddenly a group stage match in the 2007 Champions League. His first. All this within a year, so this must be a referee with a bright international future.
Euro 2008 came a bit too early for him, he was there though, albeit as 4th official.
Lannoy was selected for the Olympic Tournament in Beijing and got to officiate one match there.
Lannoy was selected for the 2010 World Cup in South Africa where he took charge of two group stage matches. The reviews on World Referee were mixed.
Yes, he will be there in 2012 too, still the only Frenchman at the top.
And Lannoy is again the only Frenchman on the 2014 World Cup long list.
