Borussia Dortmund teenager Jude Bellingham is being investigated by German police for his post-match comments about referee Felix Zwayer.
“For me, it wasn’t [a penalty]. He [Hummels] is not even looking at the ball and he’s fighting to get it and it hits him.
Zwayer was banned for six months by the German Football Association in 2005 following an investigation into match-fixing. He has since established himself as one of the top referees in Germany and is one of four to have been awarded UEFA Elite status.
