Harte told the Sunderland Echo: "After playing with Leeds for so long, I still have a strong feeling for the club. There are few people left who were there with me, but I keep an eye on what's going on.
"They've done really well this season. They scored in the 89th or 90th minute last weekend to beat Yeovil and hopefully they can keep on doing well and bounce back into the Championship.
"They've done brilliantly to get those 15 points back and if they had started on zero, they would have been about nine points clear at the top now."
