David Withers and son Michael, 11, were outside the stadium before the Premier League match when they were approached by chance and offered a unique task.
The 125-themed corner flags were just one element of a range of activities to mark the recent anniversary of the club’s first ever fixture – a 7-1 victory over Rotherham Town on September 1, 1892.
David – who has supported the Reds since the age of six – and Michael were attending their first Anfield game since returning to the United Kingdom from living in Shanghai.
Having fulfilled their unexpected duty ahead of kick-off, the father and son took up their spots on the Kop to watch Jürgen Klopp’s side as they were held to a 1-1 draw by the Clarets.
