The final whistle had not yet arrived, but some of the Manchester United supporters had already seen enough.
They watched from the away end as the Wigan players gathered around Leo, then gradually dispersed while the broadcast replayed his goal.
A few supporters remained standing with their arms folded.
Others shook their heads, exchanging frustrated remarks with the people beside them.
Beyond the advertising boards, Wigan's home support kept singing, celebrating a match that had somehow become more astonishing with every passing minute.
When the referee finally directed the players towards the tunnel, the difference between the two sets of supporters was impossible to miss.
Wigan fans clapped their players off, some leaning over the barriers to shout their names.
The away end, meanwhile, had grown noticeably quieter, more than a graveyard.
United's players walked towards the tunnel with their heads lowered, and several supporters watched them go without applauding.
