Los Blanco’s defence seemed to be in tatters when they played Rayo Vallencano, conceding two goals as they barely managed to edge out their opponents with a 3-2 scoreline.
Penalties converted from midfielder Jonathan Viera looked to threaten the early lead that Ronaldo and Benzema had painstakingly given Real Madrid early on in the match.
It was obvious to the boss from Santiago Bernabeu that Madrid needed to get back to their basics and tighten their defence if they wanted a confident win against Juventus to ensure progress to the knockout stage.
"We're attacking very well, but we're allowing too many goals," he said. "It's an important game for Juventus but for us it's an opportunity to qualify for the next stage. The sooner we do that, the better for us."
Madrid have not seen victory at Juventus since 1962, and the Italian side has bettered their Spanish rivals five times already.
Juventus forward Carlos Tevez hopes to end his goalless streak in the Champions League in the upcoming match and avenge their recent defeat at Madrid.
"Has it really been that long since my last Champions League goal?" Tevez asked when presented with the fact on Monday. "If I haven't scored for four years, then let's hope that changes tomorrow."
"We've got to win all three [games remaining]," Tevez said. "This game is like a final and we've got to play it like that."
The new Juventus stadium has seen little defeat since it opened it doors, with Bayern Munich the only team to have bested them in Turin. The Italian side are counting on their home advantage to give them the edge needed to edge past their Spanish rivals.
