Referee Felix Zwayer has explained his decision-making after two controversial penalty calls led to Bayern Munich beating Borussia Dortmund and Jude Bellingham referencing the official's involvement in a past match-fixing scandal.
Dortmund's players and manager Marco Rose were left fuming over a number of decisions that went against them in the 3-2 defeat on Saturday night.
In particular, they were left aggrieved at a contentious handball verdict against defender Mats Hummels that resulted in Robert Lewandowski converting the winning penalty.

Dortmund were also denied a penalty earlier in the game when Marco Reus went down under challenge from Lucas Hernandez.
England midfielder Bellingham questioned in a post-match television interview why a referee who was banned for six months for his involvement in the 2005 German match-fixing scandal was allowed to take charge of such an important match.
'You give a referee that has match-fixed before the biggest game in Germany, what do you expect?' said Bellingham.
But Zwayer, speaking to Sky Sport Deutschland, said of the Hummels handball decision: 'The situation was a standard corner kick.
'I see in the game that it's about a touch by Hummels. The question for me was: Is the arm stretched away from the body or not? In real time, it was not clear whether his arm was moved towards the ball.
