Manchester City lost the first game of their Premier League title defence with the 2-0 defeat at Chelsea on Saturday.
City’s setback means Liverpool are top of the table after they beat Bournemouth 4-1 on Saturday.
But coach Pep Guardiola says he is min gespin.
He says: “I said that is not going to happen. We are not here to be invincible, we are here to be champions”.
Manchester United boss Jose Mourinho, meanwhile, reckons if Financial Fair Play rules were stricter, City would lose more often.
Taking a swipe at City financial power, the Special One says: “If the Financial Fair Play makes them stop, and then we can close the gap a little bit better.”
