Manchester United striker Wayne Rooney has enjoyed preseason training under manager Louis van Gaal.
In training sessions he openly criticised his players if he thought they were not up to scratch.
Van Gaal had some stern words for Wayne Rooney on a couple of occasions, but the England striker has no qualms with the Dutchman's hard-line approach.
"He is a tough but fair manager," Rooney said.
The former Everton striker thinks the new coach has made a big impact at the club.
"He has been great," Rooney added.
"Since he has come in he has given us all a different way of looking at football, so it's been great for us and hopefully that will continue."
