FIFA 10 CLASSIC XI

Hello, i would like to ask a question. I have seen someone using CLASSIC XI in the online games. It looks interesting, therefore i unlock Classic XI, and i want to use it in playing online games. Unfortunately, i can't find Classic XI when i was playing online games. Otherwise, i can't select Classic XI as my profile too. Actually is it possible to use Clssic XI in online games? Iwould like to try to use it in online games. :) Can anyone aswer me? THANKYOU!!!! :)
