The Daily Star says he will miss Arsenal's pre-season camp in Austria this week - because he doesn't have a visa.
Boss Arsene Wenger was hoping to get the chance to finally work with his £35m man today when his squad land in Austria for four days of training.
But Sanchez will instead go to Paris to sort out his visa.
He will train on his own at the Gunners' Hertfordshire training base before the rest of his new team-mates return on Thursday.
