Bayern Munich boss Thomas Tuchel has been left furious after his side were denied a 'deserved penalty' in the 2-2 draw at Arsenal.
It was the Gunners that were left feeling aggrieved after Bukayo Saka's late shout was waved away, but the German giants have been left feeling just as angry.
The Bavarian outfit appealed for a penalty after Gabriel Magalhaes literally picked up a pass from a David Raya goal kick - believing the ball wasn't in play despite the referee's whistle clearly being heard.
The handball offence happened when Bayern were leading 2-1 midway through the second half of the Champions League quarter-final first leg tie.
It proved crucial as Leandro Trossard equalised shortly after, before Saka, who opened the scoring, appeared to be clattered over by Manuel Neuer in the closing stages.
Mikel Arteta and Thomas Tuchel had contrasting opinions when discussing their respective incidents, with the latter accusing match official Glenn Nyberg of lacking courage.

"But he admitted on the pitch that he saw the situation, but the quarter-final is not enough for him to give a penalty for a kid's mistake.
"So he admitted that he knows about the mistake the player made, that is a bit frustrating."
In his press conference, he then raged: "The referee made a huge mistake. I know it was a crazy situation.
