For the premiership, the best face pack I've seen is
this one.
1. Click on the link - it will take you to FileFront. Download the file. It will be in what's called a Zip Folder, which you need a special program to open.
2. Go to
this page to download a Zip program called 7-Zip. It's free, and very easy to use. Now you have everything you need.
3. Next, you need to install 7-Zip. Double click on the installer you just downloaded, and follow the instructions.
4. Now open up My Computer, then the C drive, and go into C

Program Files\Sports Interactive\Football Manager 2007\data\graphics\pictures\players\normal\eng - this is where you're going to put the Facepack.
5. Copy the Facepack Zip file into that folder.
6. Unzip it using 7-Zip. You should be able to do that by right-clicking on it and selecting "Extract to here".
7. Launch FM2007. When you've reached the main menu, click on "Preferences" (down the bottom). Go to Display & Sounds. Turn off the "Use Skin Cache" button. Now confirm, then close down FM2007.
8. Launch FM2007 (again). It should take longer to load this time. Go back into Preferences -> Display, and turn "Use Skin Cache" back on. Click confirm.
9. Now you're done. Load up and play.
