Paris Saint-Germain boss Carlo Ancelotti says the big-spending Ligue 1 club are \"in a crisis\" after Saturday\'s defeat to Rennes, which saw them fall to third in the overall standings. Ancelotti blasted his side for their poor performance as Rennes punished them at the Parc des Princes. Rennes, who had been reduced to nine men, pulled off a huge shock when Romain Alessandrini scored a fantastic volley in the 13th minute and did not crumble when goalkeeper Benoit Costil was sent off after Nene\'s leveller. Julien Feret scored Rennes\' winner from a free-kick as the Breton side held PSG back even after Jean Makoun\'s second-half dismissal. Ancelotti knows his side quickly need to raise their game ahead of tomorrow\'s UEFA Champions League clash against Dynamo Kiev. \"It is unbelievable. Our attitude out there was not good,\" Ancelotti told www.ligue1.fr. \"We have just lost two games at home and that is unacceptable for a team that wants to win the league. We are yet playing as a team and we are going through a bad spell. We have to change things and I am going to change things. We need to be more concentrated, more determined and harder. It is not right. \"We need speed and intensity. I am not scared to say it; we are in a crisis. We have to emerge from it quickly. If we show character and professionalism we will pull through.\" From : Fifa
