Wether PSG sees it as a blunder or not, they have lost it and Chelsea is the winners of the Club world cup, maybe next time they will try not to underrate any team so they do not get surprised or taken unaware. It was actually an unexpected act by Enrique although he did not get penalised but that was not expected of him and it was very much needless because it changes nothing.
Well, yes...
According to several sources, the reason he did this was because he didn't accept being called a "loser." Both Enrique and Jaoa Pedro had their own reasons for this unexpected incident, as reported on the following page. You're right, however, everyone should remain calm and respect the winner. They must be able to control their passions and emotions, which can cause a commotion. And of course, no one can underestimate their opponent in every match.
