Video Assistant Referee (VAR) Questions & Answers
Experiment philosophy and background Information WhatisthephilosophyoftheVARexperiment? TheaimoftheVARexperimentistocorrect‘clearandobviouserrors’anddealwith‘seriousmissedincidents’indefinedmatch-changingsituations(goal,penalty/nopenalty,directredcardandmistakenidentityfordisciplinarysanctions).Theaimisnottoachieve100%accuracyforalldecisionsasthiswouldbeimpossibleandthereisnodesiretodestroytheessentialflowandemotionsoffootballwhichresultfromthegame’salmostnon-stopactionandthegeneralabsenceoflengthystoppages.Thephilosophyistherefore:“minimuminterference–maximumbenefit”.
WhydidTheIFABdecidetoconductanexperimentwithvideoassistance? Followingmanyrequestsfromtheglobalfootballcommunityandinlightoftechnologicaladvancesinthesportsbroadcastindustry,TheIFABagreedin2014toinvestigatehowvideoassistanceformatchofficialscouldpotentiallybeusedinfootball.Basedondiscussionswithitsvariousbodies,aswellasinitialdatacollection,TheIFAB,inclosepartnershipwithFIFA’sFootballTechnologyInnovationDepartment,draftedadetailedexperimentprotocolforlivevideoassistanceandpresenteditattheIFABAnnualGeneralMeeting(AGM)on5March2016.TheIFABAGMagreedinprinciplethatanexperimentwithvideoassistance,basedonthedraftprotocol,wouldbethebestwaytounderstandtheprosandconsofvideoassistance.Insimpleterms,itwasagreedthatthetimehadcometotestwhethervideoassistanceforrefereescouldworktothebenefitoffootball.
WhodidTheIFABconsultbeforetakingthisdecision? TheIFABconsultedmanystakeholders,aswellasFAsandcompetitionorganisers,particularlythosethathadalreadymadeeffortstoanalysethepotentialuseofvideoassistance,namelytheDutchFootballAssociation(KNVB)andtheUSA’sMajorLeagueSoccer(MLS).TheresultswerepresentedanddiscussedbyTheIFABanditsbodies,includingtheTechnicalAdvisoryPanel(TAP),FootballAdvisoryPanel(FAP),TechnicalSubcommittee(TSC)andtheBoardofDirectors(BoD).TheIFABalsohaddiscussionswithvariousothersportsalreadyusingvideoassistance,includingrugby,Americanfootball(NFL),andbasketball(NBA).Inaddition,technologyprovidersworkingwiththosesportswithstate-of-the-arttechnologywereconsulted.
