Manchester United goalkeeper David de Gea angered the Leeds fans behind his goal at Elland Road when Alejandro Garnacho secured all three points for the Red Devils.
United took on Leeds for the second time in just four days and bettered Wednesday's 2-2 result with a 2-0 victory on Leeds' own patch. Goals from Marcus Rashford and Garnacho eventually broke what was a resilient Leeds backline up to that point, but De Gea's celebrations for the second sparked fury among the home faithful.
Once Garnacho's well-taken finish had hit the back of the net to all but guarantee victory, De Gea's emotions appeared to get the better of him as he wildly fist-pumped and jumped in the air out of pure joy United had won the game.
