Javier Hernandez scored against his new team as Manchester United were beaten on the final game of their North American tour.
Hernandez played the first half for his old club and the second for his new side, and made an immediate impact as he netted after just eight minutes, to the delight of the crowd at the new Estadio Omnilife.
Chris Smalling, another United new boy, levelled two minutes later but Adolfo Bautista re-established the lead for the hosts after 38 minutes and Hector Reynoso rounded off the scoring just before the hour mark.
