Wigan Athletic have announced Manchester City midfielder Jack Byrne as the club's eighth and final signing of transfer deadline day.
The 20-year-old, who has been with the Citizens for five years, has penned a three-and-a-half-year contract with the Championship strugglers.
"Jack is one for the long-term," said Latics manager Warren Joyce. "A really hungry player who we feel can develop here over the next few seasons, a real talent."
Byrne has been capped 10 times for the Ireland Under-21s side and spent most of last season in the Eredivisie with Cambuur, where he scored four goals in 27 appearances.
