Vice Chairman Ed Woodward announced on Tuesday that he will leave Manchester United after this season.
The Englishman does not give a reason, but he does so on the day his club announced that it would abandon the Super League plans.
United, along with Arsenal, Chelsea, Liverpool, Manchester City, Tottenham Hotspur, and others, has been the target of criticism for their initiative for a Super League in the past two days.
The six clubs have since withdrawn.
Woodward's departure seems to be related to that uproar, but he doesn't mention it.
“It has been an honor to work for the world's largest football club for the past 16 years,” he said.
"United are in good shape looking to the future and it will be difficult to leave at the end of the year."
Woodward, 49, has been with United since 2005.
He has been a member of the management board since 2012 in the role of vice-chairman.
He has since been under fire several times from the supporters.
Some of the club's supporters seriously threatened him at his home in Cheshire last year.
Woodward is seen by fans as an ally of the Glazer family, who are also unpopular with the supporters.
They took over United in 2005, but have been able to bring the superpower little sporting success, especially in recent years.
The last league title dates from 2013.
There were also rumors on Tuesday evening that chairman Andrea Agnelli will immediately leave Juventus because of the Super League troubles, but the club has denied that, according to various Italian media.
There is a lot of anger and misunderstanding among the fans of the participants in the Super League.
