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. Chelsea not been a favourite to win this trophy even made it more interesting wining  the trophy and for me that's exactly how it should  be, that is what sustains the excitement in the game.
