Attacker Ruud van Nistelrooy will have to miss the start of the season.

The Dutch national team player will not be able to play for about a month, as he has been suffering from hernia pains for some time now.

Ruud van Nistelrooy will have to undergo surgery next week.

With the main "Man Utd" striker injured, the opportunity to shine will be given to new "Red Devils" acquisition Alan Smith, who will form a tandem with Louis Saha.
