$15,000 parlay (4 legs) — UEFA Champions League

Sporting attracted eight high-roller bets tracked on tail.bet totaling $210,000, though none resulted in wins across settled outcomes. The largest captured wager was a $70,000 Under 6 single in a Sporting–Vitória Guimarães Primeira Liga fixture that voided. The position generated a minus-$172,000 net loss and an 81.9% ROI deficit, with seven of eight bets constructed as parlays rather than outright singles.
