The world's most popular sports team is getting ready to list its stock on the world's largest exchange.

British soccer club Manchester United priced its initial public offering at US$14 (NZ$17) per share on Thursday.

That's below the US$16 to US$20 per share price range that had been widely anticipated.

The stock will begin trading on the New York Stock Exchange on Friday as Manchester United tries to pay off more of the heavy debt piled on the club in its 2005 takeover.

The 134-year-old club, with a record 19 English championships, is one of the most well-known teams on the planet, so the IPO is highly anticipated.

But some analysts say the debt-ridden team is overvalued and the offering is dependent on investors wearing their fan colours rather than their financial thinking caps.

''It's really trading on the level of fan interest as opposed to any sort of financial interest,'' said Sam Hamadeh, CEO of PrivCo LLC, which researches privately held companies.

''A winning team does not make a winning investment.''

Half the 16.7 million shares are being sold by the team, and half by the team's owner, a company controlled by the Glazer family.

The team expects to get US$141 million out of the deal, which it will use to pay down debt. About 10 per cent of the team's shares are being sold.

The family's 2005 leveraged takeover was valued at US$1.47 billion, much of it borrowed. United carried £416.7 million (NZ$800m) in debt as of March 31. It had no debt when it was bought by the Glazer family in 2005.

The Glazers are a US family who also own the Tampa Bay Buccaneers American football team. Malcolm Glazer is CEO of First Allied Corp, a holding company with many business interests. His two sons Avram and Joel are co-chairmen of Manchester United.

After the stock offering, the Glazers will keep control of the team through Class B shares with 10 times the voting power of the stock that would be sold to the public.

The team is one of the most celebrated in the world. It claims 659 million followers and 26.9 million Facebook fans.

It is especially popular in Asia, where its games are televised and its replica shirts and other products are huge sellers.

But analysts are more sceptical when it comes to how viable as a financial commodity the team known as The Red Devils will be, because it is not a high-growth company like a tech startup and is heavily in debt.

Manchester United is hoping to expand its lucrative sponsorships and licensing deals. The team sold 2 million jerseys alone last year, and in total 5 million branded licensed products. And earlier this month it announced a US$559 million, seven-year shirt sponsorship agreement with Chevrolet.

Commercial revenue rose 34 per cent in 2011 to total £103.4 million.

But deals such as these are only one-third of the business, said Renaissance Capital analyst Nick Einhorn.

The other two-thirds comes from less-glamorous broadcast and ticket sales. Those aren't as high-growth areas as commercial revenue because prices increase more gradually over time. And ticket and broadcast revenue depends on how far the team goes in English and European cup competitions.

Manchester United's broadcasting revenue rose 14 per cent to £117.2 million in 2011. Matchday, or ticket revenue, rose 5 per cent to £110.8 million.

''I think the club has to convince investors that the growth they're getting from the commercial segment outweighs the less exciting broadcasting and matchday pieces,'' Einhorn said.

Pouring a lot of money into the stock doesn't make sense, said PrivCo's Hamadeh.

The top end of the IPO price range would value the club at about US$3.2 billion. That would make it the most valuable sports team on the planet, Hamadeh said.

It would dwarf the record US$2 billion paid for the Los Angeles Dodgers baseball team.

And slashing the debt the Glazers loaded on the club has been a constant challenge, with the commercial operation ramped up and a London suite of offices employing dozens of people to squeeze every pound out of the brand.

The team expects to report a loss for the year ended June 30, excluding a tax credit, with revenue down 3 per cent to 5 per cent.

''You're really buying a team that is way overpriced, with no financial justification for the value,'' Hamadeh said.

Analysts aren't the only sceptics. Protests have raged against the Glazers since they bought the club and delisted it from the London market in 2005.

Fans have sent more than 1 million messages against the IPO to the club sponsors and banks, rallying against the IPO and the Glazers' ownership of the team.

But others are more positive. ''It's fairly rare for a team to be in a position to go public, but obviously Manchester United has exposure to domestic and international deals where there's a lot of growth,'' said Philip Hall, a partner at New York-based investment bank Inner Circle Sports, who advised on the 2010 takeover of Liverpool by Boston Red Sox owner John Henry.

Manchester United will trade under the ''MANU'' ticker.
