Inverness manager Terry Butcher praised every aspect of his side's display after they defeated Dundee United 1-0.
The win at Tannadice puts them top of the Premiership, having taken full points from their opening two games.
"I'm pleased with the effort, the shape and the commitment - they're a great bunch of guys," Butcher told BBC Scotland.
"Everybody works their socks off. If one man gets beaten, there's another one and then another one."
Their Northern Irish striker Billy McKay scored the only goal of the game, his second of this campaign after netting 27 times last season.
And the Highlanders could have won by a greater margin had Graeme Shinnie converted a late chance.
"They took the game to United, passed the ball well and pressed ever so well," Butcher said.
"We played the game in their half nearly all of the second half.
"These boys are full of energy. It was a powerful second half, powerful.
"They know how we want them to play, especially with the work ethic, because they worked so hard pre-season and it's coming to fruition now.
"But we can play some good football, too. We've got good players on the ball and players that want to excite."
One major talking point in the contest was a late challenge by Caley Thistle's Richie Foran on Gary Mackay-Steven.
Foran caught the United winger on the knee after being skilfully outfoxed by him.
"I'll tell you what happened," Butcher said.
"The ball bounced between him and Mackay-Steven and Richie's thinking that Mackay-Steven's going to play it with his foot, but he actually plays it with his knee.
"Richie was committed and then made contact with the player's knee. It's not malicious, it's just an accidental challenge.
"Referee Steven McLean was excellent and strong and it was the right call."
