Guardiola stunned Manchester United by revealing he'd been offered their record signing by agent Mino Raiola amid growing uncertainty about the Frenchman's Old Trafford future.
“I don't have too many regrets," said the City manager. “That's the question for his agent, his comments. It's in the past.
“We lost the last game, every game is a new history and a new chapter.
“We realise how strong they are. When they dominate and create chances they win easily - but you have the feeling (even when) you are in control they punish you.
“For 75 minutes I'd like to play the same game against United as in April. But United showed us they need 10 or 15 minutes to create a lot of chances. When they have the ball and the people in front – wow – they can create something."
