Republic of Ireland under-21 international Kieran O'Hara's development at Manchester United has been rewarded with a new deal that runs to the summer of 2020.
The Manchester-born stopper made his first appearance on the bench for Jose Mourinho's senior side on the final day of the 2015/16 season against Crystal Palace.
And he's been a mainstay in Ricky Sbragia's Red Devils reserve side, who finished sixth in the Premier League 2 last season.
21-year-old O'Hara recently established himself as Noel King's first choice for Ireland under-21s and he's started all five games in the current round of European Championship qualifying.
Ireland currently sit second in Group 5 behind Germany, with three wins, a draw and one defeat from their opening fixtures and two clashes with the leaders to come.
"Since I joined United, it has been everything I expected it to be," O'Hara told the club's official website on signing his new deal.
"The club gives you all the guidance that you need from experienced coaches to improve every single day.
"But I know that the hard work has just started and that I need to continue to listen and give everything in training and the matches we have coming up.
“I know I’m at the right place to continue my development as a young player and I’m thrilled to have signed a new contract."
