Root told reporters: "I'm not really fussed. I just love playing for England. I just want to keep representing my country and do as well as I can.
"I'm doing something I've always wanted to do since I was a kid, so I don't want to ruin it with nerves or getting upset.
"I just want to make the best of it and just really enjoy the occasion and the atmosphere."
Root scored 41 runs in his new role at Chelmsford before being dismissed by former England paceman Sajid Mahmood.
