Bruce is weighing up whether to make a bid for Mido who has slipped down the pecking order at White Hart Lane.
The Egyptian finds himself behind Dimitar Berbatov, Jermain Defoe and Robbie Keane who recently signed a new long-term deal.
Mido, 24, is unhappy with the situation and almost moved to Manchester City in January before the deal was scuppered at the 11th hour.
The former Ajax, Celta Vigo and Marseille player joined Spurs two-and-a-half years ago from Roma, initially on loan, and scored 11 goals in 27 Premiership appearances in his first full season to convince the north Londoners to make the deal permanent last summer.
But Mido was restricted to just seven league starts and one goal during the 2006-2007 campaign.
Bruce is desperate to bring in new firepower and has also been linked with Preston's David Nugent.
He has four strikers at his disposal in Cameron Jerome, DJ Campbell, Rowan Vine and Mikael Forssell following the return to Arsenal of Nicklas Bendtner after a season-long loan.
But Jerome, Campbell and Vine are unproven at top-flight level while Forssell has been dogged by injuries for the past three seasons.
Blues offered Viduka £60,000 a week but it was not enough to tempt him away from the North-East after leaving Middlesbrough on a Bosman free transfer.
