It is strongly advised to have no more than 50 in your squad. You can have more, but you run the risk of having adverse effects on your club. Every week, you select 11 players for the game. All positions are different from each other.
Giving players in the original 4-4-2 setup different "extra" orders, you can arrange them in a formation different from 4-4-2. A-B-C formation means that there are A defenders in your team( including extra central defenders) + B midfieders (including extra innner midfielders) + C forwards (including extra forwards). Choice of formation is mostly directed by the skill you are training, maximizing trainable positions. There is only a number of formations that are useful in Hattrick: 3-5-2 and 4-5-1 - for midfield trainers mainly; 5-4-1 and 5-3-2 - for defence trainers mainly; 3-4-3 and 4-3-3 - for forward trainers mainly. These are formations your team can get experience in by playing matches. If you play a formation you are not experienced in, you run a risk of confusion decreasing your midfield rating. Sometimes for training purposes you might want to play other formations, like 2-5-3 or 5-5-0. But at all times be sure that you do not have more than 3 players playing on same position, or you'll lose training for the week. E.g. 3-5-2 with 2 wingers and one extra inner midfieder is perfectly legal, while 3-5-2 with a single winger and 2 extra IMs will lose you training. The players may get injured, allowing for one of your substitutes to enter the game. A player assigned "Sub (forward)" will enter the field, should one of your forwards get injured. If you don't have a substitute assigned to a certain position, or if the substitute is injured as well, one of the other substitutes will automatically get selected to play. If you don't have any able substitutes as your regular players get injured, you'll have to continue the game with 10 players. Always remember to name a goalkeeper for the game, if you don't, an outfield player will move to the goalkeeper spot, thereby disrupting your overall tactics. Also remember that you must start your games with at least 9 players, to avoid a walk over, which will lose you a week's training for all players in your squad, as well as a portion of your club's supporters.
There are five types of general tactics that you can use. These can be described as a common intention that the team has. All tactics except "Normal" have a benefit and a disadvantage, so choose carefully.
These tactics are described in detail in the Tactics section or Chapter 11 of the rules: Tactics.
This function only applies under special circumstances. If a cup game or qualifier ends in a draw after extra-time, a penalty shoot-out is held. Before a cup game or a qualifier, you should decide the order of your penalty takers. This can be done with a special orders form under the regular orders list.
Both the player's routine and his skill at set pieces should be taken into consideration. The player least skilled at these abilities should be at the bottom of this list - penalty shoot-outs rarely go on beyond the first 10 penalties. Note that the first penalty taker is always the same as the one taking the set pieces during the regular game. If you change the first name on the special orders form for penalty shoot-outs, this is the same as changing the regular orders form on set pieces. The other 10 penalty takers can only be changed around by using the special orders form.
As for the order of the first 5 penalty takers, it isn't important. All teams start off with five penalties each, and if the game is still drawn after that, it'll proceed with sudden-death penalties – each team taking one penalty each until it's all been decided.
If a team becomes ownerless (deserted by its human user) it will continue to use the standard lineup until this lineup is reset automatically. Such a reset is made 3 times each season: Before the mid-week games of Week 1 (the first cup game), Week 8 (mid-season), and Week 15 (the qualifying games). When the reset is made, all ownerless teams that have had previous human owners will revert to a walk-over lineup (0 players). Ownerless teams will thus be relegated through each series until they reach one of the two lowest divisions, where they can get a new owner. Lineup resets only apply to teams that have lost their owner, not to teams that never had one. However, this will be changed next season. Ownerless teams won't play with a walk-over lineup anymore, but they will play as a bot team.
