Stuart Seddon, a former coach at Lancaster City Youths, remembers watching the youngster in action for the Hotshots at the Giant Axe Stadium.
He told the Manchester Evening News: “His team would give the ball to him and dun, dun, dun, dun, dun he would take on five or six players and score and then would give the ball to him again and he would do the same thing!
"I went home that day and told my wife, Helen, 'I've just seen a future international captain'. I'd never seen anything like that before."
McTominay was captain of Our Lady's Catholic College's Year Seven football team.
And former assistant head teacher Ken Mangan, 57, remembers a 'likable' and 'popular' kid who was the talk of Lancaster on the field.
"He was not one of the tallest at that age but he was very strong physically. Even in the playground I saw him a few times playing with kids older than him and still holding his own," he said.
"He got around the pitch – he was everywhere – and was very, very mobile. He could strike the ball. Because it's quite a small area, all the other clubs knew that and every time he got the ball someone went to close him down because they knew.“
