A team is the virtual football team one owns and manages in Hattrick. It consists of a number of virtual football players, usually between 20 and 30 (maximum 50). The manager chooses a formation with 11 of these players for each game, plus 5 substitutes.
Each player has an individual name and ID, along with its current age, and is made up of assorted skills, personality, form, experience and specialties. He'll also have an ideal position, but you'll need to work that out through experience!
Form is one of the most important characteristics for any player, determining how well he is able to use his skills. You'll note that a good player who is out of form will often be outperformed by a not so good player at the top of his game.
Some players may not have the greatest abilities, but their knowledge of the game more than makes up for it. Thus, old and experienced players often play much better than their younger, greener colleagues.

Some of the players in Hattrick have specialties that differentiate them from other players. A player may have only one specialty, and no more.
Player's specialities are also affected by the weather, for example a Quick player will not play as well as he could in wet and rainy conditions. Also players that have Head as their speciality will be better at scoring headers/clearing headers than another player that does not have the Head speciality.
Injury and Suspension
All this is well and good, but sometimes a player isn't able to play...

Yellow and Red Cards
Players may get booked or sent off during games. Two bookings during a match will automatically lead to the player being sent off. Bookings and Sending-Offs during competitive games eventually lead to a suspensions. A player will be suspended for the next (competitive, cup or league) match if he is sent off, or if he has accumulated 3 bookings during a season. This is shown by a red card symbol on the player page. You can also see how many yellow cards have been received so far. At the end of the season all cards are cleared.
Whilst a player can receive cards during friendly matches, they have no other effects than those seen during the game.
Highly aggressive players will tend to be booked more often than other players. Especially if they're also dishonest or lacking in experience.
Players sent off will still receive training when they are not injured on training update, they dont have to play again.
