It has been widely reported that the Catalan outfit are preparing to move for the Argentine international at the end of the season.
However, Bartomeu has insisted that there has been 'no contact' between the two clubs over a possible move for a player that has scored 10 times in the Premier League this season.
"We don't have any contact with him. I can deny that completely," he told Onda Cero.
It is believed that Aguero is keen to return to Spain in the future.
