Barcelona midfielder Sergio Busquets is confident in stand-in coach Jordi Roura, who will take charge against Real Valladolid.
The 24-year-old said Saturday's fixture was very important for his side, and said they needed to win it for themselves and for coach Tito Vilanova.
Vilanova is in hospital after undergoing surgery on Thursday to remove a tumour, having suffered a relapse of cancer first suffered last year.
"Tito is the coach. He's in charge of everything. We'll all do everything we can to make the job as easy as possible for Jordi, although he's more than capable of that on his own," Busquets said.
"These are three very important points.
"On a collective level, but especially for Tito, we have to win, because there is no alternative.
"It was negative news, we've had a lot of it, but in the end we are encouraged and that gives us strength to do well in the game." Busquets was also keen to point out the dangers posed by their opponents.
"They have a really good team. I'm not only worried about their aerial ability, I'm worried about all parts of their game," he said.
"They like to play from the back, they play good football and they're having a good season. We have to think about our own game and find a way to win."
