Roberts was made available for sale during the summer by Sam Allardyce but a switch failed to materialise before Tuesday's deadline.
Allardyce, however, did name the forward in his 25-man Premier League squad on Wednesday and Roberts insists he will continue to give his all for the club despite a bleak-looking future at Ewood Park.
Roberts told the Lancashire Telegraph: "For me it is not a problem, not a problem at all.
"I am a Blackburn Rovers player and if the club wants me at any point I will do my best and will do everything I can for the team.
"I am comfortable with continuing where I am and I am comfortable with what I can do here.
"I will do my best, train hard and continue to be as professional as I can be."
The addition of Mame Biram Diouf and Benjani has frozen Roberts out of the picture at Rovers, but the 32-year-old believes he has nothing to prove after scoring more Premier League goals than any other striker at Ewood Park last season.
He said: "Football is all about opinions, I know that and I have no problem with that.
"I honestly don't believe I have got anything to prove.
"All I can do is keep doing what I have always done.
"I scored more league goals than all our other strikers put together last season and I am comfortable with my record of five goals in 15 starts.
"I believe I can still score goals in the Premier League and will look to do that if I get the chance.
"It is up to other people to pick the side. All I can do is work hard, turn up for training and I of course will continue to do that.
"I have got no problem here."
Roberts continued: "I have no clue what will happen.
"Obviously I haven't spoken to the manager yet because we haven't trained since the close of the window.
"I am a Blackburn Rovers player and I have always been available for selection and will continue to be.
"My job is to play football, I have a contract to do so and have done that at Blackburn Rovers for the last four years.
"Nothing will change as far as I am concerned."
