Roberto Mancini insisted Stoke City's goal was 'basketball not football' during Manchester City's 1-1 draw at the Britannia Stadium.
Stoke took the lead on 15 minutes through Peter Crouch, who appeared to use his hand to bring a bouncing ball into his path before slotting home.
The incident was not spotted by referee Mark Clattenburg and City boss Mancini was left aggrieved by the decision at the final whistle.
"If you want to talk about their first goal, we will talk about it," Mancini told Sky Sports.
"It was not football, it was basketball. I don't know how it's possible the referee didn't see it."
Javi Garcia marked his debut for City with the equaliser and the result means the Premier League champions have now drawn on their last four trips to the Potteries in the top flight.
Mancini added: "It was difficult because we know this every year.
"This time it was also difficult because we came here after the international break. For this reason it was more difficult.
"This is normal every year for all the teams, it is difficult to play here."
