German legend Michael Ballack reckons Celtic were robbed out of a penalty against his former club in the second half of their Champions League defeat.
Bayern stopper Dayot Upamecano trod on Celtic midfielder Arne Engels inside the box, but after a VAR review, Spanish ref Jesus Gil Manzano - who didn't book a single player - decided against the spot kick and awarded a drop ball to Bayern.
But Ballack - who won titles with Kaiserslautern, Bayern and Chelsea and was capped 98 times by Germany - reckons his old club got away with it, in his role as a TV pundit at Parkhead.
He said: "He clearly stepped on his ankle, so that's actually a foul.
"If that was in midfield it would certainly be a free kick.
"There are borderline decisions where you ask if it was a clear defensive action or was he preventing the opponent from getting to the ball?

"And that was clearly the case here for me, because he wanted to get to the ball and with this foul the defender clearly prevented him from reaching the ball.
"It doesn't matter whether it was intentional or not. It's a foul and only the assessment of the kick on his ankle is what should count.
"The referee decided that Upamecano played the ball beforehand.
"But for me, it's still a foul.
"Bayern were certainly a bit lucky in the situation. But you need that sometimes."
