Roberts is reportedly getting frustrated that he is not getting enough starts like McCarthy, with Big Sam preferring to play Franco Di Santo up front.
Benni is already looking for a move away because he wants more of a chance of getting into South Africa’s team at the World Cup.
And Roberts could follow him in January unless Sam starts using the player more in attack. Roberts proved that he can do the job when he hit a brace in the 3-1 win over Portsmouth on Saturday, but that was only after changes were made at half time as Rovers were useless in the first half.
Roberts told the Daily Star: “I’ve not been in the best of moods recently. All you can do is do the business when you get the opportunity.
“Will I still be here in January? I’ll have to see. I want to play football. The manager has decisions to make in terms of formation and personnel.”
