Hansi Flick's side suffered a 4-2 defeat to Osasuna in La Liga last weekend, but they remain at the top of the table, three points ahead of second-placed Real Madrid.
Alaves, meanwhile, have picked up 10 points from their opening eight matches of the 2024-25 campaign, which has left them in 11th, representing a solid start, but they have lost their last two to Real Madrid and Getafe.
Here, Sports Mole takes an in-depth look at the head-to-head record and previous meetings between the two sides ahead of their contest at Mendizorrotza Stadium.
Head-to-head record
Previous meetings: 47
Alaves wins: 7
Draws: 7
Barcelona wins: 33
Barcelona, as expected, comfortably lead the head-to-head record between the two sides, with the Catalan outfit winning 33 of their previous 47 matches with Alaves, suffering only seven defeats in the process.
Barcelona are on a three-game winning run against Alaves, including a 3-1 success in the corresponding match during the 2023-24 campaign, while they are unbeaten against Sunday's opponents since September 2016.
Lionel Messi is the all-time leading goalscorer in this particular fixture, having found the back of the net on 13 occasions against Alaves during his time at Barcelona.
In La Liga, the two teams have met on 36 occasions, with Barcelona winning 24 of those encounters, while Alaves have posted five wins and there have also been seven draws.
Alaves' last home victory over the Catalan giants in Spain's top flight came back in December 2001, which is an indication of the size of their task when it comes to picking up a positive result in this match.
Alaves last avoided defeat to Barcelona in October 2021, while they also held the La Liga giants to a 1-1 draw in their own stadium in October 2020, so the team are capable of picking up positive results in this fixture.
Barcelona have found the back of the net on 92 occasions in their previous 36 La Liga matches with Alaves, while the Blue and Whites have scored 32 times.
