The shirt numbers market is a football sports spread betting type that accumulates each goal scorer’s shirt numbers in a game. So, if you’re a fan of someone like Scott McTominay and you believe he has a good chance of scoring for Manchester United, then you would back the shirt numbers as he wears the number 39. If he was to score, then you are awarded 39 points for each goal. This market can be great fun for people new to spread betting and looks at the game differently.
