Manchester United has begun a partial listing on the New York Stock Exchange, in a move valuing the club at more than $US3 billion.
The club, bought by the Glazer family in 2005 for $US1.2 million, will offer a 10% stake to the public, raising up to $US330 million.
The share price is set between $US16 - $US20 each.
But some are saying that Manchester United is overvalued, particularly as it has hefty debts and faces tough competition from rivals with very deep pockets.
Sport management professor Stefan Szymanski of the University of Michigan says the club's listing success is determined by the success of the English premier league.
