Main article: Match engine

The contribution of a single player to match ratings is determined by his skills (Playmaking, Passing, Defending...), role (in defence, midfield or offence) and his position on the field (goalkeeper, defender, forward...). In other words, you have different contribution to ratings both placing a player in a new position or replacing a player with another with different skills.

Sectors

According to the Hattrick manual, match ratings divide the team in 7 sectors on field (3 of defence, 1 of midfield and 3 of attack) and, for each one of them, skills that contribute to sector ratings are:

Skill Contribution to ratings (most important first)

Defence		Midfield		Offence
Central Defence	Side (right + left) Defences			Side (right + left) Attacks	Central Attack
Defending central defenders Goalkeeping goalkeeper Defending inner midfielders Defending (left and right) wing backs Defending goalkeeper Defending (left and right) wingers	Defending side wing back Goalkeeping goalkeeper Defending side central defender Defending side winger Defending centre central defender Defending goalkeeper Defending left inner midfielder Defending centre inner midfielder	Playmaking inner midfielders Playmaking wingers Playmaking central defenders Playmaking forwards Playmaking wing backs		Winger side winger Winger side wing back Scoring forwards Passing side inner midfielder Passing side winger Winger forwards Passing forwards Passing inner midfielders	Scoring forwards Passing forwards Passing inner midfielders Scoring inner midfielders Passing wingers

Position

Starting from table above, here is how a player on field contributes to ratings with his skills, position by position:

Skills

Finally, we can find, for each player's position, the skills that contribute to ratings:

Position Contribution for each skill (synthetic view)

Player Position	Skill
	Goalkeeping	Defending	Playmaking	Winger	Passing	Scoring
	Defence		Midfield	Offence
Goalkeeper	Central + Side	Central + Side
Central Defender		Central (+ Side)	Central
Wing Back		Side (+ Central)	Central	Side
Inner Midfielder		Central + Side	Central	(Side)	Central + Side	Central
Winger		Side (+ Central)	Central	Side	Side (+ Central)
Forward			Central	(Central + Side)	Central + Side	Central + Side

Last table^[1] adds individual player orders (defensive, offensive or towards middle/wing) and a little math. May seem complicated at first glance, but it is actually quite simple. Take for example the Goalkeeper's contributions in Central Defense:

• 0.165 for Goalkeeping (i.e, the goalkeeper's Goalkeeping is 12),
• 0.079 for Defense (i.e, the goalkeeper's Defense is 6).

Then we can calculate My goalkeeper's contribution to central defense = 12 * 0.165 + 6 * 0.079 = 2.45

Adding the contribution of other players we will find the central defense rating.

If you prefer percentages to coefficients you can use this skill contribution table depend on positions of players on fields.

Footnotes

1. ^  Coefficients ​​are calculated playing a normal "away" match (without bonus to midfield), without tactics, with a balanced coach and offence ratings related to average levels of confidence. All values are increased by about 18.65% to take into account a standard amount of the parameters of form, stamina and experience. Player's loyalty bonus can be added later. No Overcrowding penalties applied.
