Bayern Munich boss Thomas Tuchel fumed at the referee's explanation for allowing Arsenal to escape punishment for a "kid's mistake" during an exhilarating Champions League quarter-final first leg.

Bayern felt they were denied a clear penalty in the 66th minute of the breathless 2-2 draw at Emirates Stadium after Gunners defender Gabriel inexplicably picked up the ball following a David Raya goal kick.
