Speaking to BT Sport ahead of United's second leg against Europa League opponents Real Sociedad, the 23-year-old Welshman has revealed the competition for places at United is pushing him to provide selection headaches for boss Ole Gunnar Solskjaer.
"It's always great for other players to come in, I don't take it as something to be down about – I take it as a challenge,'" James said.
"There's always going to be challenging moments here because we've got unbelievable players in the position I play and it helps me, it drives me on.
"I don't take that as a bad thing, at the moment it's about giving the manager a headache, I think that's what he wants, to be able to have a selection of players and not make it easy for him.
"I'd like to think I've done that from things he says every day that he's got a [selection] headache and I've got to keep giving him that."
