Champions League Semi-Final Betting Guide: Where the Value Lies in PSG-Bayern and Atletico-Arsenal

The Champions League semi-finals kick off next week, and based on form analysis, these are two of the most evenly-matched ties we have seen at this stage in years. Bayern Munich are the bookmakers' favourites to lift the trophy at 36% implied probability, followed by Arsenal at 27%, defending champions PSG at 24.5%, and Atletico Madrid the outsiders at 12%. But outright odds and match-level value are very different things — let me break down where the smart money should go.

In the PSG vs Bayern first leg at the Parc des Princes on April 28, the draw looks the standout bet. PSG have not conceded in the knockout rounds and their defensive record at home is formidable, but Bayern's attack — led by Harry Kane with 11 Champions League goals this season — will create chances. The value lies in Under 2.5 Goals at odds of around 2.10, and a 1-1 correct score at 7.00 offers genuine bang for your money.

Atletico Madrid vs Arsenal on April 29 is a different beast. Simeone's sides in Champions League knockout matches are historically low-scoring — just 1.2 goals per game across his semi-final appearances. Arsenal under Arteta have adopted a similarly pragmatic approach in Europe this season. The data strongly suggests Under 2.5 Goals here too, priced at 1.85, while Both Teams to Score: No at 2.00 represents solid value given both teams' defensive records.

For those looking at outright winner markets, Arsenal at 3.00 represents better value than Bayern at 2.75, despite Bayern being favourites. Arsenal's path through Atletico is arguably more navigable than Bayern's route past PSG, and their defensive solidity — just 3 goals conceded in 8 knockout matches — gives them a genuine edge in tight games.

Both first legs kick off at 10pm EAT, perfect for a midweek viewing session. My headline picks: PSG vs Bayern Under 2.5 Goals, Atletico vs Arsenal Draw, and Arsenal outright winner at 3.00 for long-term value.
