Barca were clearly agitated by the shock news that Van Persie has arrived in the city. Only last week Arsene Wenger said he feared the Dutchman's ankle injury would keep him out for a month.
On Monday he suggested that, along with Theo Walcott and Alex Song, Van Persie would not be here for the last-16 clash.
Guardiola said: "Mr Wenger said Van Persie wasn't going to play and today he's with the team. Last year something similar happened, so maybe there will be a private flight for Walcott to come in."
