"My plan was always just to go for the three years and then get into day-to-day running of a club job, which would be what I wanted to do," Neville told beIN Sports.
"It's been brilliant and I've loved every minute of it, but ultimately you don't get to see the players. You don't get to impact them every single day, which is now what I feel I need to do."
"I had a World Cup, I had the Olympics... and then there's the Euros in England next summer. That was my three-year stint at international football," he said.
"With the coronavirus, there has obviously been no Olympic Games, no Euros â€” which meant that obviously I had to make the decision early."
