Manchester United boss Sir Alex Ferguson admits the Premiership race is so close it could come down to goal difference with current leaders Arsenal.
"We're scoring a lot of goals and, you never know, it could be an issue. We just want to make sure that, if it goes to goal difference, our own tally is good," said the United manager. "I've always said that having a superior goal difference is worth an extra point. It could be vital this season with the championship being so close."
