However, he insists his fellow left-hander's potential return does not put added pressure on him after scoring just 89 runs in the series.
Warner was suspended for punching England's Joe Root in a bar after a Champions Trophy game last month and was sent to join up with Australia A.
He scored 193 against South Africa A in Pretoria and the 26-year-old could be in line to make his Ashes debut at Old Trafford on Thursday.
"David brings a lot of energy to the group. He goes 100mph and it is fantastic to see him get runs," Rogers told a press conference.
"He is such a destructive player so if he bats for long he could put some real pressure on England.
"He is one of those ones the opposition know they have to get out quickly.
"If he bats for a while he can take the game away like a (Adam) Gilchrist used to do.
"Hopefully he can do that for us if he does play.
"I think they used Davey in the middle order when he played for Australia A - I don't know if that is what they want to do but maybe it is.
"Darren (Lehmann, Australia coach) said we (Rogers and Shane Watson) were the openers to start but it is up to us to perform and I know if I don't perform I may not deserve a place in the side.
"The rest of the series, who knows what's going to happen? I've got this opportunity and I've got to make the most of it."
Steve Smith is a doubt for the third Test after struggling with a stiff back which prevented him practising on Tuesday.
"Steve Smith may have tweaked his back yesterday but it's improved a bit and hopefully he will be all right to train tomorrow and be good to go on the first day," added Rogers.
