Diego Simeone's stubborn and cynical side were eventually broken down in the 70th minute of the Champions League quarter-final as Kevin De Bruyne gave the hosts a well-deserved lead ahead of the second leg.
Atletico showed little appetite for the ball and relied on a handful of counter-attacks to pose a threat, delivering a typically-disciplined defensive display.
But after conceding, the LaLiga champions resorted to their infamous dark arts, chopping down City's players and demanding punishment for every small infringement.
Jack Grealish felt the full force of Atletico's treatment and Pep Guardiola was forced to intervene when Angel Correa smashed the ball in the Englishman's face as he lay on the ground.
Meanwhile, Simeone went charging down to the assistant referee after Matheus Cunha rolled around on the turf in stoppage time, before the Argentine boss snubbed a handshake with Guardiola at full-time.
Those were just a few examples - and talkSPORT host Adrian Durham could not hide his feelings towards the Spanish side after the game.
He said: "I'm going to call it as I see it: this Atletico Madrid side are an absolute disgrace.
"I'll call them horrible, cheaty, anti-football, no desire to entertain. Simeone is a ref pest.
"The players are sneaky, out-housing, Sunday League wrong 'uns.
"Atletico Madrid have no desire to play football whatsoever. If I were Joao Felix, I would ask for a transfer so I could continue being a professional footballer.
"Why anybody would want Simeone as their manager, I do not know."
Meanwhile, Wales legend Dean Saunders accused Atletico of 'parasite football' for sucking the life out of games.
He told talkSPORT: "If you want to spoil a game of football, just play like Atletico Madrid.
"They're actually trying to spoil the game. They sit back and wait. It's called parasite football - they live off your mistakes.
"They shut the doors all over the pitch and just try to intercept a pass.
"If you sit back against Man City and invite them to pass it round you, eventually they will score a goal. Then you can't get one back.
"It's terrible to watch, terrible to play in, nobody's going to enjoy it.
"If you watch Man City vs Liverpool, it's going to be entertaining. I've played like that myself, as long as you get a result - I'm not having a go at Simeone.
"But the way he's setting up, it's spoiling the game to watch, spoiling it to play in, condensing the space, showing no ambition to score.
"When you're watching the game, you fall asleep."
However, co-host Jason Cundy sprung to the defence of Atletico, insisting there should be no problem with their style of play.
Cundy told talkSPORT: "They are kings of the s-housery. They play in a very different way and they win football matches.
"If you go toe-to-toe with Man City, you're going to get thumped. I don't know whether you can criticise what they did tonight.
"You've got to come up with a formula to beat Atletico and that's the challenge for Guardiola.
"I don't have a problem with the way they play. You've got to come up with a solution and that's what City did."
