Chris Porter, United's FA Cup matchwinner at the weekend, is determined to repay the faith that Nigel Clough has shown in him.
The former Derby County striker, who worked with Clough at Pride Park, issued the pledge after scoring a decisive late penalty in Saturday's FA Cup first round victory over Colchester United.
"I've not been involved much lately but the Gaffer has given me a chance and I want to thank him for that," Porter said. "Now I've got to try and kick on.
"It would have been easy for him (Clough) to have just eased me back in slowly but he's given me an opportunity and it's one I want to try and take.
"I've played for him before and I know what he's all about. He brings a lot to the table but basically he's a very, very good manager.
"I'm not expecting any favours, though. What I've got to do is make sure whenever I'm in the team, I perform."
"Nigel showed faith in me by taking me to Derby," Porter added. "I was unfortunate there with injuries and he probably got a bit sick of me not being able to get involved or just having to sit on the bench.
"I'm over all of those now, though. So what I've got to focus on is working hard and scoring goals because, ultimately, that's what everyone in my position is judged on."
