Gill, 45, joined Manchester United in 1997 as finance director after previously being finance chief at travel company, First Choice Holidays.
He was appointed deputy chief executive in August 2000 and was promoted to group managing director in July 2001.
Gill insisted the departure of Kenyon would not destabilise the club, although he admitted that the move was a ‘bolt out of the blue’.
‘I think it’s important to stress that we’re just into the season this doesn’t detract from the football side of things,’ Gill said.
‘We’re always looking to strengthen things on the management side, and will make sure this has no effect on the football.’
