Match preview
After winning promotion via the playoffs last season, Espanyol made a slow start to their La Liga campaign, suffering consecutive 1-0 defeats to Real Valladolid and Real Sociedad.
However, they subsequently built some much-needed confidence with a hard-fought goalless away draw against Atletico Madrid, laying the foundations for them to record a narrow win over Rayo Vallecano in their final outing before the international break.
Carlos Romero cancelled out Alvaro Garcia's fourth-minute opener, before Tottenham Hotspur loanee Alejo Veliz netted a dramatic 96th-minute winner to spark wild scenes of jubilation at the Stage Front Stadium.
Espanyol will hope to give their supporters another win to celebrate in Saturday's contest as they look to record home victories in La Liga for the first time since March/April 2022.
The hosts may be able to draw inspiration from the fact they have won each of their last three home matches against Alaves, including a 1-0 victory in their most recent home encounter in September 2021.
After finishing in 10th place last season, Alaves have the tough task of replicating that success in the 2024-25 campaign.
They will be encouraged by the fact they have made a positive start to the new season, recovering from an opening-day defeat to put together a three-game unbeaten run.
Luis Garcia's charges played out a goalless draw with Real Betis, before they beat 10-man Real Sociedad 2-1 and recorded a 2-0 home victory over Las Palmas.
After extending their unbeaten home run to six league matches before the international period, Alaves return from the two-week break with a road trip and hopes of recording back-to-back away wins for just the second time in 2024.
However, that may be easier said than done because Alaves have failed to win any of their last eight competitive away meetings with Espanyol (D2, L8) since they recorded a 2-1 victory in March 2002.
