Real Madrid hold a 2-1 lead after the first leg in Germany last week.
Real manager Zinedine Zidane insists the job is nowhere near complete.
Zidane:
“The key for us is think about winning the game and go onto the pitch wanting to do that. We need to go out to score quickly and that’s what we’ll try to do.
“It’s a semi-final, we know how important it is and what we have to do. We don’t have to change what we’re doing. Our focus and determination will be there – we don’t need to change much – what we did in the first leg was good, but we now need to show in the return that what we want is to go through.”
Real’s playmaker is Isco available after the Spaniard trained on Monday having recovered from a shoulder problem. But right-back Carvajal is set to miss out after injuring his hamstring in Wednesday’s first leg at the Allianz Arena.
Meanwhile, Bayern will be without wide man Robben and defender Boateng after the duo picked up injuries in last week’s first leg.
Javi Martinez and David Alaba are expected to be fit for the game
