James has been impressive once again this term, scoring four goals and supplying four assists in 12 appearances across all competitions. He is Chelsea’s joint top scorer this season despite playing in a wing-back position.
The 21-year-old has been included in the latest England squad for upcoming FIFA World Cup qualifiers against Albania and San Marino.
Asked about his form at a press conference on Tuesday, James said: "I'd say at this moment in time, this is probably the best I've performed, and recent results and performances have probably shown that as well.
"Our team's performing well and we're creating a lot of chances, so that's obviously helping and we've got great players around us.
"When you're playing week in and week out, you're playing well and the team's performing, keeping clean sheets and winning games, it obviously helps everyone build confidence."
James will be competing for a place at right back with Trent Alexander-Arnold and Kyle Walker in Gareth Southgate’s first eleven but he maintains competition is healthy for their growth.
"Each one of us has a different style of play. Trent's obviously been at the top for quite a few years now and Kyle Walker as well, so the competition's very tough," he said.
"There are other full-backs who are not here as well who are also at a very good level. I'm competing with very good players, it's tough and we just have to keep pushing each other.
"When you come away, you know you have to put club rivalry aside and when we're here, we're one team and our aim is to win and no matter who we're playing against, we have to put it aside and focus on our task here."
