I don't think you can easily. What I would do is create your career team and insert them into the game in MY LEAGUE. You would have to decide in how great of detail you want to go when doing this editing them. If you want to match their abilities exactly it may take some time but if you just want the same players/teamname/kit then it shouldnt be too tough... It would just take a little bit of importing exporting and you're done... then you could use them in any tournament and if you choose, in the manager mode as well (but this would take editing the tournament with tournament master 06).
