The striker struggled during his last season in the top-flight with Birmingham City.
He said: "Coming from Conference to the Premier League, it was a massive step. Before when I was here it was like going into a dark alley without a torch but now I feel like I have that torch.
"The expectancy was huge. I had played in non-league and when I went to Brentford and played in front of 5,000 people that was the biggest crowd I'd played in front of.
"Then you move from that to 30,000 or 40,000 people. It's a difference that's hard to explain. It does bring pressure, I'm not going to lie.
"But I have always kept the same friends and keep my counsel with them and my family.
"I'm more prepared now. I had a taste with Birmingham and after being out of the Premier League and it made me realise how much I was desperate to get back.
"I want it so much because maybe this is my last chance."
