The Amakhosi attackers have come under heavy criticism of late following their barren form up front.
The Soweto giants have scored just three goals in their last seven PSL matches, highlighted by their goalless draw against AmaZulu on Tuesday.
Sthembiso Ngcobo netted the milestone goal for the Serbian tactician in the 2-1 victory over Free State Stars last week, but the coach is demanding an increased return when the league resumes next year.
"The last goal we scored against Free State Stars was the 100th we have scored since I took over," Vermezovic told The Citizen.
"That is 100 goals in 76 matches. That is an average of more than one goal a match. Maybe that is not good enough and people still remember the old Kaizer Chiefs.
"The other teams are also very strong. If you look at the standings, five to six teams are fighting for the title.
"We have to score more goals to better our chances but this is going to be the toughest season in the history of the league.
"Pressure is part of being at Chiefs. There is always pressure from the fans, the media and the opponents.
"I don't think it has affected us in any way. We made mistakes against AmaZulu - including Sthembiso - but we can't kick him. Mistakes are there to learn from. We have quality in our strikers."
