Harry Wilson, a 16-year-old rising midfield star for Liverpool, made his international debut Tuesday night during Wales' 1-1 draw against Belgium in World Cup qualifying.
With Wilson making that first international cap, his grandfather made a cool £125,000, for a £50 bet placed a long time ago. The BBC reports:
His grandfather Peter Edwards, 62, was quoted odds of 2,500/1 when he placed the bet with a bookmaker in Wrexham.
He is now set to retire a year earlier than originally planned.
"When he was about 18 months old he used to chase a ball around on the carpet before he could walk," Mr Edwards said.
"I went into William Hill in Wrexham and asked them how I go about it. I had no idea how to do it and the manageress put me in touch with London."
If this all sounds a bit familiar, you might remember the case of Ryan Tunnicliffe, who won his father £10,000 after debuting for Manchester United in the Capital One Cup last year.
And so the lesson here is obvious: Nothing says familial love like placing a bet on an 18-month-old relative.
