The Polish striker left Bayern after eight years to continue his career at Barcelona.
Robert Lewandowski has backed Bayern Munich to cover for his departure without signing a new striker.
The experienced striker left Bayern Munich to join Barcelona on a €50m deal last week. Lewandowski was the main focal point of Bayern’s attacking line since his arrival from Borussia Dortmund in 2014.
However, he believes his former teammates can score enough goals in his absence.
Speaking to Sport Bild, he said: “Bayern’s attack is outstanding. They can manage it very well, even without a one-on-one replacement for me.”
He added: “There’s Kingsley Coman, Leroy Sane, Thomas Müller, Jamal Musiala.
“The players are given more responsibility for scoring goals and can grow in this role.”
Bayern added Sadio Mane to their squad earlier this summer before signing a contract extension with Serge Gnabry.
According to Bild, Julian Nagelsmann is planning to use the Gnabry-Mane pair in a 4-2-2-2 formation.
Kingsley Coman and Thomas Muller will reportedly play behind the two strikers. In midfield, the pair of Joshua Kimmich and Ryan Gravenberch will stay ahead of a four-man defensive line.
Bayern have travelled to the US for a pre-season tour. The Bavarians will face DC United in a friendly game on Thursday.
