There isn't a single player I would pay to watch. You can say Thierry Henry, he's a fabulous striker, with pace and power, but a great entertainer needs to have charisma, too. Does he have charisma? No.
Owen is great and Beckham is good. Owen is direct, fast and scores goals. Beckham has other qualities which make him good, but what makes a player different is the danger he poses to the opposing defense. That's where Owen is better than Beckham.
