Arsenal manager Mikel Arteta said that he studied every penalty awarded in the competition across the last three days “to understand what is a penalty and what is not.”This comes after Arsenal were denied a penalty in the Champions League final defeat against Paris Saint-Germain. In the 11th minute of extra time, Arsenal winger Noni Madueke got in front of PSG’s Nuno Mendes and went to ground after tussling with the Portuguese left-back.Arteta and the Arsenal players appealed for a penalty though their claims were waved away by German referee Daniel Siebert, and the decision was not overturned by video assistant referees Bastian Dankert and Robert Schroder.Declan Rice, who captained Arsenal to the end of the match after Martin Odegaard and Bukayo Saka were substituted, received a yellow card for his protests, while Arteta was visibly frustrated on the touchline.Arteta protested the decision on the touchline (Carl Recine/Getty Images)Extra time ended with the score at 1-1, after goals by Kai Havertz and Ousmane Dembele, with PSG going on to retain the Champions League with a 4-3 victory on penalties.After the match, Rice told TNT Sports: “I was gutted at the time because I thought the ref would go and have a look (at a replay on the pitchside monitor), but it was obviously not clear enough to be a penalty. I thought it was and so did our bench and our players.”
