• Barcelona have made the perfect start to their title defence with back-to-back victories as they look to make it three straight La Liga crowns, something they haven’t managed since Pep Guardiola’s side achieved the feat in 2011.
• Hansi Flick’s men should be confident of continuing that winning run in this one as they’ve not suffered a defeat in the opening three La Liga rounds since 2019/20, whilst they’ve won four of their last five meetings. 
• Nine of Barcelona’s La Liga home wins last season came by 3+ goal margins, whilst they won all nineteen of their home games in La Liga, it’s no surprise to see them as the heavy odds-on favourites in this one, there could be more value in the handicap market with William Hill.

• Rayo Vallecano impressed last season especially on the European stage, although The Red Sashes fell short in the Europa Conference League final, losing 1-0 to Crystal Palace.
• Their campaign this season has started off slowly, a defeat at Sevilla was followed up with a stalemate against Alaves eleven days ago, not since 2018/19 have the Red Sashes opened a campaign without a win in their first three games, that run is expected to end here.
• However, if punters fancy a repeat of Rayo Vallecano’s visit back in 2022 in which they took all three points, they can be backed at 14/1 to do so with William Hill.
