Zinedine Zidane hopes other Real Madrid players will come to the fore after Cristiano Ronaldo rescued a point against Athletic Bilbao on Wednesday.
A late Ronaldo flick - his 42nd goal of the season - denied Bilbao a rare victory at the Bernabeu, with the 1-1 draw leaving Real third in La Liga, 15 points behind leaders Barcelona with five games remaining.
The point all-but ends Real's league defence, though they do maintain hopes of securing a third successive Champions League title - a feat last achieved when Bayern Munich won the European Cup from 1974 to 1976.
Bayern stand in Real's way this season, and Zidane insists his side cannot rely on just Ronaldo when heading to Munich for the semi-final first leg on Wednesday.
"We can think there will be other players as well as Cristiano who could make the difference in Munich," Zidane told reporters.
"We have to stay focused because it's a Champions League semi-final and we're defending our title."
Against Bilbao, Real fell behind to an early Inaki Williams strike and failed to respond until the 87th minute, despite hitting the bar and forcing a number of fine saves from Kepa.
However, Zidane said he was not worried by Real's lack of goals, and reiterated that there is no issue with Gareth Bale, who failed to impress after coming on as a second-half substitute.
" Bale hasn't got any problems. I've got 25 players and Bale is one of them. He's not started and there are others who play and do a good job," Zidane added.
"I'm not worried [about the lack of scoring]. We've had chances in the last few games without scoring many but we shouldn't think too much about it."
"We have to be optimistic, we can't be looking at and listening to what you're saying, we'll concentrate on the positive elements. It's only been a couple of games. We have to focus on Wednesday's match to turn this around."
