Europe's premier club competition is hugely popular with football punters, so the best bookmakers often compete to attract business with Champions League betting offers and Champions League free bets. These promotions can be used to bet on hundreds of pre-match, outright and in-play markets at the best Champions League betting sites.
Our expert team has scoured the internet in search of the best football betting sites in the business since Gambling.com was founded almost two decades ago.
As part of our bookmaker review process, we compare and recommend offers from bookies that are licensed by the United Kingdom Gambling Commission.
When testing out Champions League free bets, we sign up with bookmakers, make deposits and claim their offers for ourselves. This gives us first-hand experience so that we can rule out any offers that don't treat bettors fairly.
We also try out promotions like money-back specials and odds boosts before recommending the best of these deals to our readers - while our price comparison process means we'll never opt for sites that don't have competitive Champions League odds across a range of markets.
