He scored a hat-trick as Villa were beaten 4-0 at West Ham and was also on the mark as the Hammers won 2-1 at Villa Park.
"When I got here some of the players remembered that hat-trick at Upton Park.
"They told me I had to make up for that by doing the same thing for Villa now against other teams. That's what I want to do.
"Of course the manager has made it clear that he cannot guarantee me a place in the starting side.
"I don't mind that. It makes me want to go out there, train hard and show the manager what I can do. Hopefully that'll be enough to get me into the team.
"When there's competition, that means people are doing it on the pitch, so it is going to be hard for me. But it's a long season, so maybe there'll be some chopping and changing. Our formation seems flexible anyway, so I'll be looking for a chance to fit into that."
The striker concluded: "I want to get back to my best. I'd really like to do for Villa what I did a couple of years ago with West Ham.
"That team couldn't wait to get up and running in the Premier League. We really did well that year, getting to the FA Cup Final.
"Now I see the same thing at Villa. I think it's time I started enjoying myself again."
