FC Barcelona vs Feyenoord Prediction & Best Bet

Best Bet: FC Barcelona to cover -2.5 spread (-152)

Few teams in the early stages of the 2026/27 season have been as dominant as Barcelona. Los Blaugranas are coming off a 5-0 thumping win over Valencia in their previous LaLiga match, and Hansi Flick's men have scored at least five goals in three of their first four LaLiga matches while also keeping three clean sheets. It's too early to make a judgement call, but they have the early look of a contender.

Their opening match of the 2026/27 UCL campaign looks favorable, as they'll face a Feyenoord side that is not only considerably inferior in quality, but also entering the game depleted by injuries. 

The Rotterdam-based outfit is undefeated through their first five Eredivisie matches (W3, D2), but having conceded at least two goals in three of their last four league fixtures, it's hard to see them going up against Barcelona's elite attack and coming away unscathed. Look for Barça to deliver another high-scoring win in front of their fans to kick off their European campaign on a strong note, as they've covered the -2.5 spread in three of their four wins in 2026/27.

Liverpool vs Atletico Madrid Prediction & Best Bet

Best Bet: SGP: Over 2.5 goals and both teams to score (-121)

If Liverpool were to be defined in one word following Andoni Iraola's first three matches in charge, the word would probably be "entertaining." They kicked off the season with back-to-back 2-2 draws against Newcastle United and Nottingham Forest before securing a 2-0 win over Ipswich Town. Their free-flowing attacking style has exposed some defensive weaknesses, but their games have been pretty open.

The same could be said about Atletico Madrid, with their last three games featuring over 2.5 goals while posting a W1, D1, L1 record. They're coming off a 3-0 loss to Athletic Club that snapped their undefeated start to the Liga campaign. With both teams showing far more talent in attack than in defense, and neither side having a clear path to fixing their issues at the back, this game has the makings of an open contest. These two sides met in the 2025/26 UCL season, and Liverpool secured a 3-2 victory at Anfield. That exact scoreline has also happened in three of their previous four head-to-head meetings.

Napoli vs Arsenal Prediction & Best Bet

Best Bet: Under 2.5 goals (-110)

Napoli came close to pulling off an upset against Inter Milan this past weekend, but defensive mistakes doomed them in a 3-2 loss as Inter delivered a furious second-half comeback. Napoli have lost two of their first three 2026/27 Serie A matches, and they need to tighten things up defensively if they're going to contend against an Arsenal side that boasts a perfect record through four competitive matches in 2026/27.

The Gunners began their campaign with a commanding 3-0 victory over Manchester City in the Community Shield before dispatching Coventry, Aston Villa and Chelsea in the Premier League. The Blues have been the only team to breach Mikel Arteta's defensive scheme, and they should rely on their defensive prowess to get past Napoli, who have scored in every game this season but have struggled against top teams.

I'm backing Arsenal's defense to come through in this match despite the absence of William Saliba, and given Napoli's woes on offense, I believe this game will err on the side of the under.

Barcelona, Liverpool and Arsenal headline Wednesday's Champions League Matchday 1 slate, with our best bets targeting Barcelona's spread, goals in Liverpool-Atletico and the under in Napoli-Arsenal. Check the latest odds and projected lineups before kickoff.
