Hate to be the contrarian jerk again, but Guivarc'h was an oustanding striker back then. He came to the world cup after two spectacular D1 seasons at 20+ goals. I still remember some of these goals.
But, yeah, he achieved absolutely nothing at the WC and that was pretty much the end of him (except for another successful late season with Auxerre). It's unfortunate something went wrong at that point in his career, because he most certainly had the skills. And let's not pretend he was any worse then futtbuck, drooling fuck-tard Dugarry, who only made the team because he was BFF with Zidane and Liza. (yeah yeah, he did score one and Guivarc'h none)
