Who is favored to win? According to Bookmaker 2, Genk is the favorite with odds of 1.85. This implies a 54% chance of winning (more likely than not). A £10 bet would return £18.50 if they win (£8.50 profit).
What about Basel? The odds of 3.50 suggest a 29% chance of winning (unlikely). However, if you bet £10 and they win, you'd get £35.00 back (£25.00 profit) — higher risk, higher reward.
How likely is a draw? Draw odds of 4.00 imply a 25% probability. A £10 bet on a draw would return £40.00 if correct (£30.00 profit).
How to read odds: Lower odds = more likely to happen (but smaller payout). Higher odds = less likely (but bigger payout if correct). Multiply your stake by the odds to calculate your total return.
