Matthaus cites Dortmund's 7-1 win over Celtic as one reason why Bayern will ease through tie.
Defender Trusty was still clearly a happy man at Celtic training this week before Bayern clash.
Matthaus believes that Celtic will pose 'no danger' to his former club Bayern Munich.
At the top of a match preview, the headline reads: 'Five reasons why Bayern Munich will progress against Celtic in the Champions League'.
They also point to their eight-point lead in the Bundesliga, which enables Bayern boss Vincent Kompany to concentrate on Celtic, despite a match against second-placed Bayer Leverkusen coming up on Saturday.
