Hart spent a period at Elland Road as academy director and was instrumental in the development of current stars such as Harry Kewell, Alan Smith, Jonathan Woodgate and Paul Robinson, to mention a few, before taking the same position at the City Ground in 1997.
He is also a former player at Elland Road of course.
Hart is almost half-way through his contract as Forest manager and is understood to have been fancied by some members of the Leeds board after Terry Venables was sacked before they opted for Reid.
