Aberdeen manager Derek McInnes took exception to Inverness counterpart John Hughes highlighting the gulf in playing budgets between the clubs.
It followed the Dons' 3-2 win in the Scottish Premiership at Pittodrie.
"I'm disappointed in John Hughes' comments about budgets, because it's easy to say that when you've lost a game," McInnes told BBC Scotland.
"John worked at Hibs when his budget was strong, but budgets don't guarantee anything."
McInnes thought that Aberdeen's success was built on "good players, good work ethic, good honesty".
However, the Dons boss himself highlighted that their victory came despite having to do without the injured Niall McGinn, Russell Anderson, Clark Robertson and Ryan Jack.
"It was an exciting game, but I always thought we were going to win, even when we went behind and even when they equalised," said McInnes.
"We are a little more open than maybe we were last season, but when they are as good as they were today, it is worth persevering with."
McInnes was particularly delighted with the "excellent" performance of strikers Adam Rooney, who opened the scoring, and David Goodwillie.
He thought that their energy forced mistakes out of the Caley Thistle defence, with poor pass-backs leading to two of the Dons' goals.
Hughes shouldered the blame for those errors.
"I am not pointing the finger of blame at anyone," he said. "That's the way we play.
"We have an open, expansive style of football and I ask the boys to get on the ball and play football and I've no doubt we are going to make mistakes.
"I take full responsibility because I want my boys to be brave.
"I am just proud at the way they took the game to Aberdeen and for long periods of the game played real good football."
Hughes added that he was pleased that his side were able to compete so closely with the Dons.
"We are a provincial club," he said. "We don't have the budget of a club like Aberdeen.
"All credit to the boys - I'm proud of them. Aberdeen knew they were in a game and at times we played some right good football.
"We could be a little bit more clinical and defend a bit better, but let's give Aberdeen respect - they are a good side.
"But we love being underdogs and coming to places like Pittodrie and giving it a right good go."
