Attacker Javier Hernandez will miss about a month of matches due to injury. The Mexican, who has scored six goals in the English Premier League this season, got injured at the beginning of the match against Aston Villa and had to be substituted. "I think it's a hamstring injury," said Man Utd manager Sir Alex Ferguson after the 1-0 victory. "Javier will be out of the lineup for three or four weeks." Another striker, Michael Owen, is also nursing an injury, leaving Ferguson with fewer attacking options than usual. However, Danny Welbeck, who came on as a substitute on Saturday, is available for selection again. "At the moment we are struggling with injuries. At least we have depth on the bench," added the English champions' manager.
