Manchester United executive vice-chairman Ed Woodward will step down from his role at the end of 2021.
It comes amid widespread criticism of the proposed European Super League (ESL), with Manchester United one of six Premier League clubs to have initially signed up to the plan.
United’s rivals Manchester City withdrew from the ESL on Tuesday and Chelsea are also planning to do so.
Woodward, 49, had been in the role since 2013.
He was set to leave at the end of the year but the decision to announce his departure has been brought forward.
After plans for the ESL were announced on Sunday, Woodward stepped down from his role on Uefa’s Professional Football Strategy Council.
Woodward had significant input into the discussions around a revamped Champions League on Friday.
Uefa had hoped the new 36-team Champions League, which was agreed on Monday, would stave off any breakaway Super League, but the controversial competition was announced on Sunday.
Uefa president Aleksander Ceferin was critical of Woodward, saying that the United man was “very satisfied” with the reforms when they last spoke on Thursday evening.
Ceferin added that Woodward only wanted to to discuss financial fair play but “obviously he already signed something else”.
Manchester United co-chairman Joel Glazer will be a vice-chairman of the Super League
BBC Sport has been told the agreement between Woodward and owners the Glazer family is amicable and there has been no falling out.
The announcement was brought forward because of the prospect of leaks.

Louis van Gaal and Jose Mourinho were also dismissed for failing to match expectations.
