This document establishes a source-informed evaluation method, not a supplier league table. It does not verify current match-level coverage, negotiated club prices, real error rates, contract-specific rights or adoption outcomes. Those require authorised samples, actual agreements and club participation.
The research reviewed official product and technical pages, league materials, public contract terms, regulator guidance, job-board evidence, industry reporting and practitioner podcast/webinar pages. Podcast descriptions and supplier webinars were used as discovery/context sources, not as proof of product accuracy. The linked SkillCorner YouTube recording could not be retrieved for independent review; no claim here depends on having watched it.
