Pumas have agreed to join the Florida Cup on short notice after Arsenal and Inter pulled out, and they will play Everton next Wednesday.
The Gunners had several members of their organisation test positive for Covid-19 just before embarking on their pre-season jaunt across the Atlantic, and the Nerazzurri followed their lead in cancelling their U.S. plans as a precaution.
That left only Everton and Millonarios in the competition, but Pumas have agreed to lend a helping hand, ensuring the tournament will continue. Atletico Nacional of Colombia have also signed on to meet Millonarios next week.
