He said: "I will make a few changes to the side but it doesn't mean that I am underestimating Bradford or dismissing the competition.
"Our priority at this club is to remain in the Premiership, but a cup run is good for players' confidence.
"You also have to entertain your fans and that is what I expect. There will be a few new faces in the side compared to the team at Sunderland last Saturday."
And Robson is delighted to come up against old friends from his time at Valley Parade.
He added: "There are still a few players there who played under me. They are good professionals.
"There were some really good professionals at Bradford. The only frustrating part I had from the Bradford days was when they went into administration.
"I lost half the team and that became frustrating. It was another learning curve where you experience things in the game.
"I didn't spend any money at Bradford. When I brought in the loan players we had a really good run but for whatever reason the chairman at the time decided not to put any more money into the club.
"The loan players had to go back and the best two young players, Andy Gray and Simon Francis were sold to Sheffield United. It made it very difficult.
"I remember we beat Rotherham 2-1 away from home and on the Sunday morning I got the telephone call saying the club were going into administration. A lot of people at the time said to me that I hadn't gone into the job in those circumstances so why didn't I leave.
"But you get attached to the players who are working their socks off for you.
"Plus all the players were deferring their wages. So that is why I stuck with hoping that we could get out of it despite losing half the team.
"It is very difficult to walk away from players who were trying their hardest to keep the club alive. That is why I remained at Bradford."
