fter yet another disappointing result on the road against Levante, Barcelona return to the Camp Nou in need of a response on Tuesday.
They host Slavia Prague, the team that they struggled past just a couple of weeks ago in the Czech Republic, in the Champions League.
A win would see them take a considerable step towards the knockout stages and further consolidate their position at the top of the group.
The Champions League has offered Barcelona a refuge from their difficulties in LaLiga Santander and, after the humiliating defeats to Roma and Liverpool in previous campaigns, they've found some form in the competition.
Ernesto Valverde will be without Luis Suarez, who suffered a calf injury against Levante, but has an otherwise fit squad to choose from.
It's not known who will join Lionel Messi and Antoine Griezmann in the front three, with Ousmane Dembele, Ansu Fati and Carles Perez all in the reckoning.
WarningsSlavia may head to the Camp Nou as the bottom placed team in Group F, but Barcelona know all about their qualities after their trip to Prague.
Messi's early goal gave the visitors the lead before Jan Boril equalised for Slavia shortly after half time. The points went Barcelona's way thanks to Peter Olayinka's own goal.
The match prompted a thorough self-examination within the Barcelona dressing room in the hours and days afterwards.
Slavia are still unbeaten in the Czech First League, winning 13 and drawing two of their 15 games this season.
