Frank confirmed "everyone available last time is available again" after Saturday's draw at Brighton, though the Doncaster game comes "just too soon" for Randal Kolo Muani and Ben Davies, who have "minor injuries".
Dominic Solanke and Kota Takai are "progressing" and trained with the team on Tuesday.
On Dejan Kulusevski's recovery: "Of course, Kulusevski is a top player. I have always liked him when I saw him from afar. He is a key player for us and a key player for me. Instead of putting an exact month, I just want him back as soon as possible. It's not tomorrow, but hopefully it's not too far away."
Frank is keen to give his young players minutes: "It will be a great opportunity to have some of the young ones on the bench. It's a privilege to be able to give someone a debut. Obviously, they have to show it in the under-18s, under-21s, national team and with us to get the opportunity."
However, he stressed the importance of taking the Carabao Cup seriously: "I would like us to compete in all four tournaments across the year. If you're going to do that, you need to pick the right team all the time. Every time we put a team out there it is super strong. We need to hit that perfect number of players that rotate and a strong team."
More on rotation: "There will be some rotation but there should be, with all respect to Doncaster. They have Grant McCann, who I know very well. He is a very good guy and we need to respect his team, but we need to play to our highest level and get to the next round."
His target is to win the trophy: "I don't know any coach or manager or player that doesn't want to compete and try to win. We are really looking forward to going into the Carabao Cup tomorrow and will do everything we can to try to win it. We play for that."
On the decision to allow Doncaster's on-loan Damola Ajayi to play against his parent club: "We decided to loan him out because it is good for his development. We weren't that lucky to face one of our own players. It is a great opportunity for him."
