The former Bristol City striker/winger penned a two and a half year deal with the Reds last week and made his home debut in Saturday’s 1-1 draw with Swansea City.
And the 23-year-old former Ipswich Town, Millwall loanee and England Under-19 international is now ready to “re-launch” his career having admitted it had been at a “standstill” this season.
“I feel this club can help me became the best player I possibly can be,” said Haynes, who is expected to play his first South Yorkshire derby away to Doncaster Rovers tonight at the Keepmoat Stadium.
“I feel as though my career was at a standstill. I felt I had to come here and re-launch it.
“I want to score goals and enjoy myself here. I need to get the best out of me. I thought this was the right move for me. I personally don’t think I got enough games at Ipswich and I came off the bench a lot. I just really wanted to start and play more games.
“At the start of the year I had a bad injury at Bristol City and I was out for a very long time.
“They [the club] brought players and they started to do well - and I haven’t managed to get back in the team. It was just of those things really, the timing wasn’t great.
“But I know I’ve got the ability and I know I’ve got the talent and now I feel I’m at the right club to bring that out of me.”
Haynes added: “It was pretty hard to judge how well I played [against Swansea] to be honest because I haven’t had a whole match for a while now.
“But I felt as though I worked hard and hopefully when I get my fitness up more I can show what I’m about.”
Reds boss Robins was impressed with Haynes’ debut in Saturday’s 1-1 home draw with the Swans and revealed one of the key reasons he signed the player is his ability to play as a winger and a striker.
“He [Danny] worked hard [against Swansea] and we’ll see more of that,” said Robins. “He can play in a couple of positions, which gives us scope to change things.
“He’s young, he’s hungry and he wants to do well. He’s got a young family and made a big commitment to move from London to play up north.”
Haynes scored on his debut only to be left disappointed after his clinical first-half strike against the Swans was cancelled out for offside.
“I’m disappointed for Danny because he’s reacted to his chance very well, put it into the back of the net,” added Robins.
“But I’m sure the goals will come. I’m looking forward to seeing him get better and better.”
Centre-backs Stephen Foster and club skipper Jason Shackell are both expected to return to the Reds starting line-up for tonight’s re-arranged clash with Rovers, while winger Jim O’Brien has recovered from the injury which forced him off against the Swans.
