Kraft: I will only buy a club if cap is introduced

American billionaire Robert Kraft is only interested in buying a European football club if a salary cap is introduced. The American, who owns NFL's New England Patriots and the New England Revolution in the MLS, was interested in buying Liverpool before Tom Hicks and George Gillett Jr. took over the Premier League club in 2007. "I love the Premier League and we probably wouldn't seriously consider coming in unless there was some sort of salary cap," Kraft said. "We are involved in the NFL and in Major League Soccer, and we are happy to compete where it's a level playing field. "We don't want to be a business where the wallet determines what kind of player you have. Anything we are going to be involved in, the franchise must be in the best position to win all the time." Kraft remains on the lookout, though, to expand his sports portfolio into football across the Atlantic. "We've looked at some clubs on the continent," he said. "The ideal model is to develop young players and have them come into your system, but to then sell them off goes against my grain ... but if the money starts taking over and you are paying players fantastic sums sometimes the incentive isn't there to play hard every day. "I don't blame a player for wanting to get paid as much as they can, but in the end the greatest rewards in team sports come when great players subjugate their egos to the team." Speaking ahead of Sunday's NFL game at Wembley Stadium between the Patriots and Tampa Bay Buccaneers, Kraft said he believed England and Germany could each be home to an American football franchise.
