A Foul Won is defined when a player wins a Free Kick or Penalty for their team after being fouled by an opposing player.
There are no fouls won for a Handball, Dive, Back Pass, Illegal Restart, Dissent, GK 6-second Violation or Obstruction where a free kick is conceded.
- Handball – A deliberate handball by an opposition player.
- Dive – A deliberate attempt for an opposition player to deceive the referee and win a Free Kick.
- Back pass – A Pass picked up by a goalkeeper when played from a teammate.
- Illegal restart – An opposition player has consecutive touches directly after a dead ball situation.
- Dissent – A player shows dissent towards a match official.
- GK 6-second violation – A goalkeeper picks up the ball and holds onto it for longer than 6 seconds.
- Obstruction – A player traps the ball between their legs to stop an opposition player from playing the ball.
The attempted delivery of the ball from one player to another player on the same team. A player can use any part of their body (permitted in the laws of the game), to execute a Pass. Event categorisation includes open play Passes, Goal Kicks, Corners and Free Kicks played as a Pass. Crosses, Keeper Throws, and Throw-ins do not count as a Pass. Opta adds a whole range of qualifiers to each Pass event, so that various things can be measured.
- Chipped Pass – A lofted ball with an intended recipient. Must be over shoulder height and using the Pass height to avoid opposition players.
- Headed Pass – A header when there is an intended recipient.
- Launch – A long high ball into space or an area for players to chase or challenge for the ball.
- Flick-On – A glancing Pass with head or foot onto a teammate when the ball is helped on in the same general direction.
- Pull Back – A Pass inside the penalty area which is pulled back.
- Lay-Off – A first time Pass away from Goal when there is pressure on the passer (typically played by a forward) with one touch when they have their back to Goal from the Goal-line to the centre of the penalty area.
- Through Ball – A Pass splitting the defence for a teammate to run on to.
- Tap Pass – A short Pass after a dead ball situation which cannot have a lost outcome.
Each Pass is logged with X and Y co-ordinates for its point of origin and destination.
This allows Opta to log the following:
- Passes broken down by area of the pitch for example, as own half/opposition half or defensive/middle/final third or left/right/centre.
- Passes broken down by distance, for example short/long, short medium/long.
- Pass direction, for example backwards/sideways/forwards.
In summation the event-based nature of the data is such that you can calculate any combination. For example, a Chipped Pass over 20 yards, in the final third, that goes sideways.
A Tackle is defined when a player connects with the ball in a legal, ground level challenge and successfully takes the ball away from the opposition player. The tackled player must be in controlled possession of the ball to be tackled by an opposition player.
A Tackle Won is deemed to be when the tackler or one of their teammates regains possession because of the challenge, or that the ball goes out of play and is safe.
A Tackle Lost is when a tackle is made but the ball goes to an opposition player.
Both are categorised as Tackles, but the outcome of the Tackle (won or lost) is different based on where the ball goes after the Tackle.
A goalkeeper preventing the ball from entering the goal with any part of their body when facing an intentional attempt from an opposition player.
Saves have the following attributes:
- Body Part – Hands/Feet/Body/Fist.
- Save Type – Caught/Collected/Parried Safe/Parried Danger/Fumble/Fingertip
- Goalkeeper Movement – Diving/Standing/Sliding/Reaching/Stooping
This includes unintentional or misplaced efforts on target from a goalkeeper’s own teammates, but only if the intervention is not perceived to be a routine collection of the ball.
If after a goalkeeper’s intervention, a more prominent defensive action from a teammate prevents the ball from entering the goal, this will be categorised as a Block for the teammate, not a Save for the goalkeeper.
If the ball goes behind the goal because of a goalkeeper intervention, the match officials must award a Corner for it to be recognised as a Save.
