Manchester City boss Pep Guardiola has told Manchester United fans the days of the Sir Alex Ferguson era will never return.
Guardiola thinks such an era of dominance will be impossible to repeat.
"Maybe not in the way Sir Alex Ferguson controlled in those days because in that moment I think there were two or three teams (serious competitors)," said Guardiola.
"Now, Arsenal are back and Newcastle have arrived. Chelsea are in the process to restructure a few things. They will do it in the next years with the manager they have and the investment..
"Look at Spurs, how good they are playing. They will be fresh all season with one game a week. All these teams are there."
