Holt has inked a new deal, putting to bed talk of him following Paul Lambert to Aston Villa.
He said: "It's a good appointment. I spoke to Chris this week and he told me his plans and what he wanted to do, and he told me he wanted me to stay, which was the main thing I wanted to hear. As I said to Chris, you speak to the board and get it sorted this week and I'll do it.
"My goal has been reached because I got my three years. Obviously there are things I can't really say too much about. There were things said in the last six weeks that maybe shouldn't have been, and we've resolved them.
"We sat down, spoke about it, dealt with it and we will move on. At the end of the day, we're all here to keep this club where it is. I have to do that on the pitch and they've got to do that with the finances."
Holt added: "My situation made me a little unsure as it was, and with Paul going it added to it. But you've got to get on with it. All I could do was worry about my own stuff and make sure I was ready for the season, wherever that was going to be - and thankfully we got the deal done and it's here."
