Cape Town - Manchester City manager Pep Guardiola laid into the Mitre ball used during the goalless draw in an EFL Cup fixture against Wolves at the Etihad Stadium saying the 'light' ball made it impossible to score.
City secured a place in the quarter-finals of the Cup competition winning 4-1 after a penalty shoot-out after a scoreless 120 minutes thanks largely to out-of-favour goalkeeper Claudio Bravo.
The former Barcelona manager though spent most of his post-match interview hitting out at the quality of the English Football League's match ball.
"The ball is not acceptable to play with... at that level," the City boss said.
"We play with a different ball. It's not Nike, Adidas I don't know, it's a different brand. It's unacceptable to play with the ball.
"That ball is not a serious ball for a professional game. I say that because we won, eh? If I don't win, I don't say that because after that it's excuses. As I won, I can tell you: it is not acceptable to play.
"If it's for the marketing, for the money, for many reasons, it's okay but it's not acceptable to play with that ball. No weight, nothing.
"(We get the balls for) one day or two days, but the ball is bad two days, one month, one year, two years. It's bad, it's bad. The ball is unacceptable for the high of level of the competition.
"All the players complain. I assure you all of them say 'what is that?' Really. I am sorry Carabao Cup."
