The Blues boss knows that clubs are reluctant to part with their players in the January transfer window especially if they are still involved in European competition.
Bruce was on the trail of the Inter Milan forward following Blues promotion to the top flight three summers ago but that trail went cold and the player moved to Monaco on loan at the beginning of this season.
Kallon is rumoured to be interested in a move to England with a fee of around £3million thought to be needed to persuade the Italians to part with the player.
