At the summit of the steepest stand in the Estadio Nuevo Mirandilla, a couple of Manchester United supporters unfurled a blue and white triband flag and chanted "Argentina".
There was no segregation, so United fans' support for a country the United Kingdom was in conflict with 40 years ago bemused the Andalucians during the friendly on Thursday night. The Mancunians were supporting United's present Argentine, Alejandro Garnacho, and the other in Qatar.
Lisandro Martinez has forged such an ardent bond with United supporters that when the Brazilian Casemiro leapt imperiously to equalise in added time at Chelsea, the celebratory chant was "Ar-gen-ti-na", so fervent were Martinez's celebrations. A steward had to haul him out of the Shed End.
