Carter has been a versatile player for several years, being utilised as a right-back, left-back and centre-back under Sarina Wiegman and Chelsea manager Emma Hayes.
The defender admits she has “asked herself the question every single day” whether her versatility has stopped her nailing down a regular spot in the team, or has helped her get into squads regularly.
“My versatility is what’s got me into games, it’s got me playing in some of the biggest games you can really ever play in,” she added.
“It’s definitely something that’s a massive positive, but at the same time sometimes I do wish I could just play this one position, absolutely smash it, then I wonder what level I could get myself to.
“But at the end of the day you’ve got a job to do.”
Carter was left out of the starting XI for England’s second group game, a win over Denmark, but returned to the side for the 6-1 thrashing of China and has retained her spot.
“I know it’s probably going to sound really bad but when I didn’t play against Denmark I just thought ‘I’ve [already] played in a World Cup.’ I had more minutes than I thought I was ever going to get,” she added.
“I didn’t come into the tournament expecting to play at all. I was so honoured to be part of the team. Obviously, of course, you always want to play every minute but I wasn’t too disheartened.”
