The manager changed all of his outfield line-up at the interval, with only goalkeeper Martin Dubravka completing the full 90 minutes at Estadio Nuevo Mirandilla where goals from Carlos Garcia and Choco Lozano in the first period and Ruben Sobrino and Tomas Alarcon in the second gave our hosts Cadiz their 4-2 victory.
Anthony Martial replied from the penalty spot midway through the opening half, and Academy midfielder Kobbie Mainoo made his mark by equalising just a few minutes after coming on at the break.
The fluid build-up to both goals will have pleased Ten Hag and no doubt there will be other positive moments, as well as areas for improvement, to pore over as he takes his squad back onto the training pitch in the next few days ahead of another friendly, against Real Betis on Saturday (17:00 GMT) which will also be shown live on MUTV.
