Ole Gunnar Solskjaer suggested Daniel James won't waltz straight into the first team at Manchester United after the club confirmed his signature.
The Red Devils parted with £18million to land the winger, who has put pen to paper on a five-year deal at Old Trafford with the option of a further season.
Solskjaer revealed his delight in completing his first signing on United's official website, where he listed James' many attributes.
But the Norwegian also suggested the youngster will be a squad player for the time being, despite possessing the attributes to one day become a Man United star.
"Daniel is an exciting young winger with lots of skills, vision, exceptional pace and a good work ethic. He had a great season with Swansea City and has all the attributes needed to become a Manchester United player," said Solskjaer.
"We are delighted he has signed with our club and we are all looking forward to working with him. This is the perfect environment for Daniel to continue his development."
James lost his father recently and admitted his pride in signing for United is understandably tinged with sadness.
"This is one of the best days of my life and a challenge I am really looking forward to," said James.
"The Premier League is the best league in the world and Manchester United is the perfect place for me to continue to develop as a player.
"This is an incredibly proud moment for me and my family, however, it is tinged with sadness that my father isn't able to share this experience with us.
"I am looking forward to working with Ole, meeting the team and getting started."
