Guardiola told reporters: “Normally the ball goes inside from these shots. It's difficult to control it. Many years, many players and managers say about that. When you lose it [sounds like] you're complaining but the ball is not right. I’m sorry. In many years it's happened in the FA Cup and Carabao Cup, I know it's a business and they come to agreements.”
He went on to say when asked if he has asked for the relevant balls to be changed: “I've said it for many years. I'd like to play Champions League when we play on Wednesday, we play on Saturday... play on Sunday. There are things out of our control.
“I’ve said my opinion and the people say fine or not fine. We won so people will be nice to me but if we lose I would think the same. I would not say it because I don’t want to be punished but it’s the truth. The Champions League ball is exceptional, the Premier League ball is exceptional, but this one is not good.”
