The Wales winger has moved to Elland Road after two years with Manchester United.
"I haven't spoke to anyone about (my position) but I'm happy to play anywhere in the team," he said.
"I'm not going to go in and expect to walk into the team because it's a great group of players, who are playing very well.
"But I think everyone in that team in the forward line can play anywhere so, yeah, for me I've played most positions - striker, left, right - and I'm happy to play any of them."
On his new career move, James said: "I've got to go in giving my all.
"Now it's just about enjoying this next chapter of my career and just how it unfolds.
"I obviously have my own personal goals which I keep to myself, but I'm looking forward to it. I'm excited to learn, getting to learn this new system and hopefully contribute to the team."
