Leeds sustained two defeats in their opening two games of the season, but they managed to bounce back against Hull at Elland Road on Tuesday.
“I’m delighted after losing our first two,” Grayson said. “We knew it would be difficult after Hull had a good result at the weekend (winning at Ipswich), but we were good with and without the ball and made a really good Hull team look ordinary at times.
“The players were excellent from start to finish. It’s great for the players. They showed tremendous spirit, great attitude, belief and confidence.
“The results we have had could have had a negative effect. We were down to the bare bones tonight, with no strikers, (Jonny) Howson and (Max) Gradel suspended and (Leigh) Bromby and (Ben) Parker injured,
“So it’s a massive result. It’s embarrassing when you see your team in the bottom three, but I had immense belief and confidence in the players to get results.”
