John McEnroe says the Williams sisters, while playing winning tennis, lack respect and humility. The mellowed bad boy of the sport took the sisters to task in a column in Britain's Sunday Telegraph newspaper.
"What they have achieved is great, but they have no respect for anyone in the game," McEnroe wrote.
McEnroe objected to comments by Serena Williams, who last year said she would like to play in a couple of men's tournaments. "Do women golfers say they could go out and beat Tiger Woods?" he asked. McEnroe also accused Venus Williams of displaying a lack of humility while winning Wimbledon.
McEnroe restated his opinion -- earlier expressed to the New Yorker magazine -- that "a lot of male college kids and members of the seniors' tour could beat the sisters."
