"When I was 16 after the World Cup in 2010 that's when I really fell in love with the sport," he told BBC Sport. "I feel like that's obviously really late, to be 16 and just really starting. At that point I didn't understand tactics, I didn't understand technique really, so the only way I was able to be involved was as a goalkeeper.
"I played baseball, basketball and American football, those were my main three sports growing up. A lot of the attributes you need to be successful in those sports, you kind of have to have as a goalkeeper as well."
Turner had some good examples to follow, as he highlighted fellow New Jersey native and former Manchester United and Everton star Tim Howard as his role model.
"The first goalkeeper I really watched very closely was Tim Howard," he said. "He's someone with a multi-sport background as well and he's also from New Jersey, which was another piece that I really felt like I could align. Just because somebody said I couldn't do it, I didn't want to then stop doing it, I loved playing."
