Scholes highlighted Rooney's poor record at major tournaments as one of the reasons why he thinks the 28-year-old's career might be on the wane.
Rooney failed to score in the eight appearances he made in South Africa and Germany.
In fairness to the striker he carried injuries into both tournaments, but this time he has been so determined to go to Brazil in full health that he took two fitness coaches with him to Portugal on his week off.
Gerrard thinks that kind of commitment should be saluted.
"He's worked hard this week and he decided to do his own week of extra training," Gerrard said.
"He seems in an awful better frame of mind going into this tournament than he's had going into previous tournaments when he's had injuries on his mind in the past. I'm excited about where Wayne Rooney is at."
Roy Hodgson was equally dismissive of Scholes' comments.
