The former player told Talk 107 he would be interested in a return to the club in a coaching capacity, despite leaving the capital side in May 2005, after being offered a lesser role by the Hearts hierarchy.
He said at the time: "Everyone knows what the club means to me and it was a fantastic opportunity to come here. It hasn't left a bitter taste in my mouth".
Robertson spent 16 seasons with the club as a player, scoring 261 goals in the process and would no doubt be greeted with open arms by fans should Romanov choose to offer him a return to the club.
The hitman, who became known as 'The Fat Striker' during his playing days, holds God-like status among the Jambos faithful after notching an unprecedented 27 goals against arch-rivals Hibernian.
