Two of Adam’s friends tell BBC Newsbeat they previously felt safe while playing football, but Adam’s death has changed things.

“In the weeks and months after, I got two or three cardiac tests, I was pretty scared,” says George Callie, who grew up playing football with Adam.

“I was playing football four or five times a week.

“This can happen to anyone and I was OK. But it does affect you.”

The 19-year-old from Risborough says he supports the coroner’s recommendation.

“I think it’s really important that you learn how to deal with that if you’re going to be on the side of a football pitch,” he says.

“I think there’s got to be some sort of rule where between the referees, the two linesmen and the two coaches, there’s five of you, I think if two or three of you are able to carry out the procedures then that’s more than enough people to save a life, and it shouldn’t always be on the referee.”

Tom Gough, who was a close friend and teammate of Adam, agrees he “wouldn’t feel so safe” stepping on to a pitch now “because of the circumstance that happened with Adam”.

“I think there’s always going to be a bit of me that’s worried that something like this might happen again.”

The 19-year-old from Wycombe, who spoke at Adam’s funeral, says his death took a “big toll” on his mental health but it would “mean the world” if it led to change.

“If Adam’s death is the reason one or two or how many kids’ lives could be saved on the pitch, I think that is a great thing,” he says.

“Trying to take the positives out of a negative situation.”
