Boss sets challenge for Annerson
The former England under-19 international, who has joined from neighbours Sheffield United, has signed a pre-contract agreement at the League Two club.
Annerson, 20, has previously had two loan spells with the Millers and will sign on July 1.
Robins told the Sheffield Star: "I want Jamie to make it a real competition for the No 1 jersey and to push Andy."
