The promoters of Elton's gig at Leicestershire County Cricket Club next summer are expecting a surge in ticket sales in the coming weeks.
Ticket sales for the pop mega-star's performance at Grace Road are already "really strong" according to Marshall Arts but are expected to rise as Christmas nears.
Ben Martin, of Marshall Arts, told the Mercury: "There are two reasons for that.
"He closed the Royal Variety Show at the Albert Hall recently and that will be televised on December 8.
"We are trying to maximise the capacity by the positioning of the stage."
It is expected some 15,000 to 16,000 Elton fans will attend the concert on June 11.
This week, the cricket club held a meeting for residents near the ground in Aylestone to address concerns about the traffic impact of large numbers of people heading to the venue.
Aylestone ward city councillor Nigel Porter said: "People were really positive about Elton John playing but naturally there were some concerns about traffic access.
"People who live nearby want to be able to access their homes.
"The club has said it will carry out its own transport assessment and there was talk of a park-and-ride service running from the football club."
