The 27-year-old picked up the problem during Real's 2-1 Champions League win over Bayern last week and will miss the return leg at the Bernabeu tomorrow night (7.45pm). "But we'll have a chance to win in Madrid".
Bayern Munich coach Carlo Ancelotti has warned his players they can not afford to let Cristiano Ronaldo out of sight when they take on Real Madrid at the Santiago Bernabeu on Tuesday. "At the end of the day, we're not so pessimistic".
"Lewandowski is a great player and his return is very helpful", Ancelotti added. "It will be very hard in Madrid but we still have confidence".
Lewandowski has scored 38 goals in 40 appearances this season but Real Madrid midfielder Casemiro says they are wary of Bayern's whole team, not just their center forward.
11 - None of Bayern's past 11 Champions League games have ended in a draw (W7 L4) since their last-16 match at Benfica last season finished 2-2.
Real Madrid will face Bayern Munich on Tuesday. Should the 11-time European champions go all the way again then it will be the fourth season running in which a Spanish club has triumphed, indicating the balance of power in European club football is firmly back with LaLiga.
"It is clear we come here with a disadvantage, but we come here still alive".
"I have said many times I have unforgettable memories of my two years here, that is what is important".
Real Madrid's head coach Zinedine Zidane scratches his head during a press conference after a training session on the eve of the Champions League quarterfinal second leg soccer match between FC Bayern Munich and Real Madrid at the Valdebebas stadium in Madrid, Monday, April 17, 2017.
It was a chance that Cristiano Ronaldo grabbed emphatically as a second-half brace secured a 2-1 win and brought up 100 goals in European competition for the four-time Ballon d'Or victor. Madrid captain Sergio Ramos is set to play his 100th game in the competition.
When asked about who would play alongside Cristiano Ronaldo and Benzema on Tuesday, Zidane said he had; "already decided", who would start, "but I can't say any more than that", he added. Defenders Pepe and Raphael Varane also have been ruled out because of injuries.
Defeat in the home leg has left the German champions with a mountain to climb, but they have the quality to turn the tie around.
The striker should be joined by first choice defensive pair Mats Hummels and Jerome Boateng, but both face a race against time to be fit.
"I hope he will be with us [for Barcelona] but we have to wait and see".
