City boss Guardiola spoke before the final on Friday and called on fans to behave, despite the tension likely to be palpable.
“I will ask our fans to behave properly first and, secondly, go there to enjoy an incredible event,” said the Spaniard.
“The players will give everything to beat Man United. The consequences and the result, who knows?
“I don’t know. Erik ten Hag doesn’t know it, so it’s going to be a football game.
“Enjoy the moment. When the people travel – unfortunately with the train strikes – enjoy [the occasion] and enjoy next week to prepare the [Champions League] final, dream to see the team. It’s the best way.
“It’s a football game, everything can happen. We will do everything to beat United.
