The 14.24 out of London Euston, heading towards Northampton, was not a football train. Its first stop was Watford Junction, but the carriages were populated by shoppers and families. Vicarage Road was not their destination.
But there was one man, kitted in a vintage red and black Manchester City away shirt, with two large bottles of Staropramen lager partially supped and mobile phone in hand. He kept refreshing his live score app.
The train left the station just as the dramatic events at the London Stadium concluded.
The internet caught up.
