The Brazil international has missed early practice on both days since the club resumed activity, a pattern that has not pleased coach Vanderlei Luxemburgo
Extra reports that the former Barcelona and AC Milan player has slept through morning practice on both days since the club resumed training, following a break for the end of the season and the holiday period.
Ronaldinho alleges that his failure to turn up is related to bouts of insomnia that are preventing him from sleeping well in the Ninho de Urubu accommodation in which he is currently based.
Luxemburgo, however, is doubtful over the veracity of Ronaldinho's story and believes that the late starts are related to an over-indulgence in the local nightlife. The star has barely trained since activities began on Tuesday and sources close to the coach believe that he will not tolerate further excesses from his charge.
Ronaldinho recently committed his future to the Brazilian club for 2012 after disputes over non-payment of wages threatened to cut short his time with the institution.
