Sanctions are looming for London coach Arsene Wenger and midfielder Samir Nasri for improper conduct during the Champions League round of 16 match against Barcelona. Wenger did not hide his anger after referee Massimo Busacca sent off striker Robin van Persie for a second yellow card. The Dutchman received his second warning in the second half when he kicked the ball into the net after the referee's whistle. The player later defended himself, saying that he simply did not hear it amid the noise. At that time, Arsenal was leading 3-2 overall, but being in the minority, they conceded two goals and withdrew from further competition. The players of the London team were also furious and attacked Busacca. One of the most active was Nasri. "This decision killed fantastic match. If it had been a serious foul, then I understand. But in these circumstances, it is disgraceful," Wenger said.
