The coach is a very important figure in Hattrick, responsible for training speed.
Abilities of a coach
The type of coach that is best for your team will largely depend on your training type. See Coach tactics for more information.
These coaches have a attacking nature and there for stimulate the team to play more offensive, i.e... boosting the teams attack ratings.
Opposed to the offensive coach, these coaches have a defensive nature, i.e. boosting the team's defence ratings.
These coaches have no offensive or defensive preferance, and therefore boost both the team's attack and defense ratings a little.
A talented coach knows the right methods of training, allowing young players to improve their abilities faster. Training (see Chapter 17) becomes more effective. The skill can never be better than excellent.
Even if a coach is good at planning training activities, he might be a bad leader, not inspiring players to give top performances during games. The team spirit might be spoilt if the coach is a weak leader.
Changing the coach
If your coach disappoints you, you can always get a new one. There are two different ways to go:
Recruit a coach externally
Recruiting externally basically means that you hire a new coach. However, you first decide how good you want him to be (trainer skill and leadership) and what trainer type you want (one who favours attack, defence or is neutral).
Each combination of leadership/trainer skill has a fixed price. Then you "buy" him (he is taken from an unseen pool of unemployed coaches - coaches are not included on the transfer list.
Use existing player
This alternative can be somewhat cheaper than the external recruiting - if you have a player with the right coaching material.
There are a few restrictions: The player's experience determines how good a coach he can become. Also, the more experienced he is, the lower his price for a certain skill level. Players keep their leadership (already known to you) and you do not pay for their leadership - so, if you have a very experienced player with high leadership, this can be a real bargain.
However, to prevent daytrading of coaches-to-be, we have another restriction: The player must have been in your squad for a season (16 weeks) to be eligible to become your coach. While it will still be possible (in principle) to purchase a player in order to make him coach for a little less, it will require more than a season's foresight.
When you hire a new coach, he becomes the coach of your squad (when he arrives, which may take up to a minute after you ordered him) and the old coach stays in the squad (in case you want to keep him as player). If you don't want him, you will have to fire him. He can never become coach a second time for your team (although he may go to another team eventually). Also, you cannot sell a player who has become coach. This is important, as otherwise people would start trading coaches and that is not the kind of system we want. All new teams get initial coaches who are of equal skill level (weak).

Level of the coach
All new coaches of a certain skill level are equal. That is, if you purchase a coach with passable skill, he always becomes "average" passable. There is no "high passable" and "low passable". However, the increase in the coaches performance between levels is, like with regular player skills, non-linear. This means that the gap between a solid coach and an excellent coach is smaller than the gap between a passable coach and a solid coach in terms of the effect of the training, so a high-level coach might not always be the best solution for you. The common consensus on this matter is that a solid coach is both affordable and advisable for most managers.
Coaches will slowly have their leadership skills deteriorate. Deterioration will not start until the coach has been in the club for more than a season. HT's reasoning is a coach that might seem bustling with energy and inspiration when he first arrives, after a few seasons loses some of his "edge". He has simply grown bored with the job.
Finally, once a coach reaches disastrous leadership (and that would typically take perhaps 10 seasons for a coach starting with solid leadership), the deterioration starts hitting his trainer skills instead of the depleted leadership. Let us underline that the deterioration is very slow, although it will go somewhat faster for coaches with very high leadership, so a solid leader might go down to passable after 1-2 seasons (more likely after 2 seasons or more though).
Players who become coaches have an emergency surgical procedure and if they had any injuries, they are automatically healed!
