James scored six goals last season and produced six assists.
He told the club's website: "I know my ability and how well I can strike a ball. Whenever I get the opportunity, I always try and score and give myself the best chance of scoring or getting an assist.
"Full-backs were just full-backs before, but now they're trying to use them as an extra player. We have space there and sometimes it works in your favour.
"It's great when you get high up the pitch and attack but sometimes the game is more difficult and you can't do that because you're defending more. In football, anything can happen and counter-attacks happen every game, so you have always got to remain switched on and not go to sleep."
James signed a new six-year deal earlier this season and added: "It's always good to sign a new contract, to know that you're stable and going to be here for a long period.
"The last few years have been good, but we've been to finals where we've lost as well. We want to win every competition we enter, and if we get to the final, there's no reason why we shouldn't be going all the way.
"There have been a few where we've got there, but there have also been a few domestic trophies that we haven't picked up, which needs to change."
