hey
i was cleaning my room the other day and came across good old WA, now i wanted to play it against my brother trough LAN.
Everything works fine except we cant find out how we can add CPU controlled teams to our game.
Is this not possible or did i just look over it ?

Not possible. CPU players can only be added when matches are played on just one computer.

It is a feature planned for a future release of the beta updates for WA though.
