Lewandowski had a hand in all four of Bayern’s goals on Saturday as they beat Chelsea 4-1 in the second leg of their last-16 tie to book a place in the final eight.
The Bundesliga champions will now face Barcelona in the quarter-finals after they claimed a 3-1 victory over Napoli – with Lionel Messi once again proving key as he scored a sublime goal.
While Messi is renowned for both creating and scoring goals, Lewandowski also showcased his all-round ability against Chelsea as he contributed two assists, while finding the back of the net twice himself.
“We’ll see that on Friday. Lewy will have to answer this question,” Muller told reporters.
“Messi also played very well today. But it’s up to Lewy and us to answer this question in Lewy’s favour on Friday.”
Asked about Barcelona, Muller added:
“Barca may not have won the Spanish championship and they have certainly revealed some problems, but anything can happen in these knockout games. Any run can end there if you have a bad day.”
