Robert Kraft, the billionaire owner of the New England Patriots NFL franchise, has once again spoken out about the possibility of buying into a Premier League soccer club, with Liverpool his favoured destination.

Kraft, who watched Liverpool's 2-0 win over Premier League Manchester United on television before seeing the Patriots beat the Tampa Bay Buccaneers, owned by the Glazer family, again expressed his interest in a Premier League move, but confirmed he would not enter a league where success is so dependent on finance. Kraft has often expressed his belief that the Premier League should have a salary cap and other measures in place, similar to the NFL, to encourage fairer competition.

"We don't want to be a business where the wallet determines what kind of player you have," he told the press at the weekend, before adding to the New York Times: "At some point in the future there's a good possibility we could be involved.

"I'm a very big fan of the Premier League. I would probably want to see some kind of salary-cap potential to get into it, but we have all kinds of opportunities come to us in this area."

On Sunday, some 5,000 Liverpool fans took part in a protest march against the team's current owners, American businessmen Tom Hicks and George Gillett.
