Nicky Butt has left his role as Manchester United's head of first-team development.
The former United midfielder spent nine years in various coaching and development roles at the club’s academy, overseeing the progress of players such as Marcus Rashford, Scott McTominay, Axel Tuanzebe, Dean Henderson and Mason Greenwood.
He says he now wants to pursue "a new professional challenge".

"Having come through the academy myself to play almost 400 games for Manchester United, it has been an absolute privilege to come back and work with a new generation of talent making that same journey," he told the club’s website.
"I’m proud of the role everyone on the staff plays in giving our young footballers the best possible chance of fulfilling their potential, and the results are clear to see in the increased number of homegrown players reaching the first team.
I already know from my playing days how difficult it is to leave Manchester United, but it feels like the right moment for a new professional challenge and I look forward to exploring opportunities that build on the great experiences I’ve had here over the past nine years.
United manager Ole Gunnar Solskjaer said Butt had been “a great source of guidance and inspiration to our academy players”.
He said: "Nicky will always be a legend of Manchester United as a six-time Premier League winner and, of course, an integral part of our Treble-winning team.
