Viduka remains the subject of constant transfer speculation with his existing contract due to end in the summer and serious talks yet to start between the club and the player.
But Southgate insisted he did not want Viduka to go anywhere after watching him sweep Boro into a first half lead then do all the work for the second goal, which was bundled home by Aiyegbeni Yakubu.
