The thing about France is that... How many people are actually born in France that play in the team?
Also with regards Zidane. There should be no excuse for that headbutt.
I dont think there is any unfairness involved about the French team consisting of so many froeign born players, if anything, it should be a shining example of how beneficial intergration is to the host country!
I think an immigrant can serve the interest of a country as zealously and distinctly as an other citizen.
Examples that readly come to mind are General Shalikashvili in the US, Medeline Albright, and a lot more. So people should applaud the French soccer team example and value unity over division.
