You can install the Zidane trikot with TXD-Workshop (I used version 4.0b).
In TXD-Workshop open the "player.img" from the "models" folder of San Andreas.
Then choose the shirt you want to replace in the list on the left. For example "tshirtwhite.txd"!
Then click on the Import button and choose the "zidane.png" file.
There may be some grafic errors (white areas) in the preview for some reasons i don't know, but you can ignore that. In the game it will look fine.
Then click "save TXD" and it's done.

Close TXD Workshop and start the game.
Go to the shop and buy the tshirt you just replaced.
Now you should look like Zizou :)

Have fun !!
