Chief executive David Gill insists Manchester United remain on the right financial path following the emergence of Manchester City as a Premier League powerhouse.
United's ambition was questioned by Wayne Rooney before he performed a dramatic U-turn and signed a new five-year contract last week.
The England striker was linked with a move across Manchester to City where reports claimed the wages on offer were far in excess of what United could offer.
But despite increased competition from their local rivals, Gill is confident that United remain on the right track.
Asked if City's new financial muscle was a concern, Gill replied:"No not really. I'm not concerned by that as ever since we have been a public company we have had a policy that wages should be 50 per cent or less of turnover.
"We believe we can do that and still retain and attract the stars we need on the pitch. We think that's the sensible model.
"Clubs have other models – that's their prerogative. Each to their own."
