Paris Saint-Germain coach Carlo Ancelotti has admitted that he has been disappointed by the recent performances of Javier Pastore. The 23-year-old has scored a goal and claimed four assists in Ligue 1 this season, but was replaced by Nene at half-time in last weekend\'s 4-0 win against Troyes, and did not feature in Tuesday\'s League Cup defeat at Saint Etienne. \"I\'m disappointed by his performances, the player is as well I think,\" Ancelotti told a press conference. \"He\'s working hard at the moment, these past few days he\'s been training twice a day,\" said Ancelotti, adding that for this reason Pastore would \"surely be used tomorrow\" for the Ligue 1 trip to Nice. \"It\'s surely not easy for him at the moment,\" added striker Ezequiel Lavezzi. \"Like any player when he losses confidence he can\'t show his characteristics and qualities. If he can play and gain in confidence no one can have any doubts about his qualities as a player.\" Pastore joined PSG in a €42 million deal in the summer of 2011. From FIFA
