He was referring to the clash at the Bulls' rugby fortress between defending champions and table-toppers Supersport United and Chiefs, who are eight points adrift.
Vermezovic said the game would also be a test for this generation of Chiefs players, because it was the most important of the season.
He adds that a win for the Amakhosi will make the league campaign much more interesting.
When the two clubs last met in a league match, back in August, Gavin Hunt's Supersport won 1-0, leaving Chiefs in some disarray.
Chiefs' back-up goalkeeper Thela Ngobeni got a broken jaw while standing in for Itumeleng Khune.
Kaizer Motaung Jnr was booed again by the fans when he failed to score from countless opportunities and was substituted in the 67th minute.
Chiefs went on to lose their next game, against Wits, and before they knew it they were bottom of the log after only six games.
Vermezovic believes the stakes are even higher this time around.
He said he rated United highly and described them as the best team in the country.
Supersport have lost only one league game, less than anyone else in the league, and have scored the most goals.
More than half of their 33 goals have come from winger Daine Klate (8), defender Morgan Gould (5), midfielder Anthony Laffor (3) and striker Glen Salmon (3).
It's these players that Vermezovic has grown to respect.
"Laffor is the most dangerous player there," he said. "Klate is also dangerous, but I like Laffor and his type of football."
The Chiefs coach's admiration for the Liberian international is understandable. Laffor has shown class this season and scored twice in United's previous league match, against Maritzburg United at the weekend.
But Vermezovic was quick to calm any anxieties about Laffor and the other United goal-scorers.
"They did not score all those 33 goals against us," said the coach. "And we are not going to be defensive - that's not my style."
