Brockie was the top scorer in 2015/16 with 18 goals in all competitions.
However, the New Zealand international was disappointed with his return of 11 league goals.
“I've stated already that I was disappointed with the 11 league goals that I got last season. I was up and down at the start of the campaign,” says Brockie, who last week penned a new four-year deal with Matsatsantsa.
“So the 20-goal barrier hasn’t been broken for a while and that's a personal goal for me and if I can get that, it will lead to the success for the club as well. So I will try to get it.”
AmaZulu hitman Siyabonga Nomvethe was the last player to score 20 goals in a season in 2011/12.
Meanwhile, Brockie says his game has grown under ex-Kaizer Chiefs boss Stuart Baxter.
“I've enjoyed my 18 months here and I'm happy to extend,” he says.
“This club is going in the right direction. I want to keep working under Stuart Baxter, he developed me a lot in the last four or five months last season. So if I can continue to work under him win more trophies and develop as a player, I think this is the right club for me.”
