What is Expected Goals?   The Expected Goals method, otherwise known as 'xG', is the most powerful stat that can be used to analyse football. Put simply, it measures the quality of chances that teams/players are creating and conceding. It forms the basis of Tippett's first book, The Expected Goals Philosophy, which sold over 20,000 copies entirely on Amazon via self-publication.
 
xG was developed in a niche corner of the online football analytics community. It wasn't long before professional gamblers caught on and began using xG to turn over millions of pounds from the bookmakers. Eventually, a handful of pioneering football clubs caught wind of the metric and began using it across several verticals.
 
They used it in recruitment, identifying hidden gems in the transfer market. They adapted their style of play in an attempt to create fewer, higher quality chances (which proved more successful at generating goals than taking multiple long-shots). They used it to scout upcoming opponents, as well as analyse their own performances.
 
Expected Goals has finally been accepted amongst the mainstream football community in recent years.
