Manchester United boss Louis van Gaal admits he could feel the fans' frustration during victory over Burnley. Van Gaal has received widespread support from the United fan-base since his appointment last summer, but he heard whistles from the home support towards their own team in the first half and that is a worry for the 63-year-old.
"I heard the first whistles," the United boss said.
"That is a concern because we are playing for the fans.
"The fans are the most important part of the club.
"They keep the club living and that is very important but they also applauded after the match and always in matches there is 90 minutes, not 45."
