Wayne Rooney believes Manchester United will still be a success this season despite their present struggles.
Rooney was visibly unhappy with some of his team-mates' performances. But he says the future is bright.
"A lot of people seem to have written us off because of Sunday's result but I don't see it that way," he said.
Rooney, who was appointed captain by Van Gaal this season, added: "When I look around our dressing room and see the quality we have and the manager's unbelievable attention to detail I have no doubts this team will be successful."
They have lost three times, including a 4-0 Capital One Cup second round loss at League One MK Dons last month.
Van Gaal's team are 12th in the Premier League and face in-form West Ham at Old Trafford on Saturday.
