Football teams is a page in the Hattrick menu where you can select your favourite real life football teams.
These teams are shown on the manager info page.
You can select a maximum of 5 teams.
Teams are added by GMs, so when your favourite team isn't in the list you can contact them to fixt this.
However in some countries they added a selection of teams (for example all professional teams) and don't allow other requests.
