Athletic Bilbao will be looking to put their troubled start to the season behind them against fellow strugglers Osasuna at San Mames.
Bilbao, last season's Europa League runners-up, have managed just one La Liga win out of six, and after slumping 2-0 at Real Sociedad are languishing in 18th place.
European competition has offered little respite either, as Marcelo Bielsa's men were beaten 3-1 away to Sparta Prague.
The build-up to that match was dominated by the bust-up with Spain international centre-forward Fernando Llorente, who stormed out of a training session after being criticised by Bielsa in an incident which was filmed on Basque TV station EITB.
Then, Argentinean Bielsa had to face questions about a leaked audio recording of him criticising his players after last season's Copa del Rey final defeat.
Bielsa, though, expects a response.
He said: ``I can't ignore the bad streak. We are losing to teams that are inferior to us. We cannot ignore this.
``The players have played with heart and passion, and we looked like a dynamic and offensive team that never quit.
``However, when we finished attacks they found it easy to organise themselves. That is a tactical aspect that has to do with positional issues and for this, I am at fault.''
Bilboa will be without Venezuela defender Fernando Amorebieta after he was sent off against Real Sociedad.
Osasuna are a place below Bilboa in the table and finally recorded a first win when they beat Levante 4-0 last weekend.
Manager Jose Luis Mendilibar said: ``This is good news for our keeper and strikers, because keeping a blank sheet was as important as scoring and winning the first match this season.
``Next Sunday we will have another tough game at Bilbao, so we have to keep working hard.''
