The Belgium striker scored 19 goals in 34 appearances for Villa last season, but has so far hit just four in 11.
"Christian is a quality player, he's a strong personality and the goals will come," Agbonlahor told the Birmingham Mail.
"It's down to us as a team to keep creating the chances for him. That's our job as well.
"After last season there's going to be a lot of expectation on him. He's still doing well in training, he's working hard, so the goals will come."
Agbonlahor himself is yet to score this season.
