Ruben Amorim put up a passionate defence of Casemiro as he insisted that the Brazilian showed he "cares" with his reckless red card against Chelsea. The Brazilian midfielder had already found the net to double United’s lead, only to undo his own good work with a reckless challenge just before half-time. Already carrying a yellow, he lunged into another rash foul, leaving the referee with no choice but to send him packing.
