Wayne Rooney: Critics wrong to write off Manchester United, we will be successful under LVG
Striker Rooney, who was appointed captain by the Dutch boss in the summer, could not prevent Leicester turning over United on Sunday.
A 3-1 lead for United slipped away as Leicester claimed a stunning 5-3 victory at the King Power Stadium.
United stand 12th in the Premier League after five matches, already eight points behind leaders Chelsea.
Expectations of a major improvement after last season's seventh-placed finish have been formed on the basis of the appointment of the experienced Van Gaal and the recruitment of players including Angel Di Maria, Daley Blind, Radamel Falcao, Luke Shaw and Ander Herrera.
And Rooney is convinced the blossoming of the team will materialise, taking issue with those doubting United's ability to respond to their current frustration.
Rooney wrote on his Facebook page: "There seems to be a lot of people who have written us off because of Sunday's result but I don't see it that way.
"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."
