Bochum coach Marcel Koller claimed new disciplinary directives in the Bundesliga go too far after being sent to the stands during Friday night's 1-1 draw at Hannover.
Koller was shown the red card 10 minutes from the end of the Bundesliga fixture, becoming the first man to feel the full force of a new disciplinary clampdown.
The stance was introduced in the wake of several problems last weekend, when the likes of Stuttgart goalkeeper Jens Lehmann, Werder Bremen's Claudio Pizarro and Dortmund pair Robert Kovac and Jurgen Klopp got in trouble for criticising officials.
But after last night's game, Koller insisted he did little to deserve a red card.
"I got a bit wound up about a decision by the referee, but I did not insult him in any way," said the Swiss coach. "Emotions are part of football."
Referee Michael Kempter defended his decision to send Koller to the stands by revealing the Bochum coach "had repeatedly complained" about his decisions.
Hannover coach Dieter Hecking also had a lot to complain about after the match.
His side went ahead just after an hour through Jan Schlaudraff, but an own goal by Florian Fromlowitz shortly afterwards prevented them from moving clear of the bottom three.
"We wanted all three points here but we have only got one and that is certainly too little," said Hecking. "We have got to start picking up points away from home."
The result lifted Bochum temporarily out of the bottom three while Hannover are just three points above the drop zone in 13th place.
