City continued their prolific goal-scoring record against the hapless Burton Albion in the League Cup semi-final first-leg.
"The result was good and of course we are already in the final but we have to play the second leg", said Guardiola.
Gabriel Jesus also offered a major contribution thanksa to his four-goal haul and he admitted that it was the first time that he had achieved the feat in his career. He has insisted his side go out and give a proper account of themselves in the match, and to respect a competition he won twice as a player.
"With the quality of the runs they make and the delivery of the ball, Premier League teams and the best in Europe can't stop them, so I don't know what little Burton Albion are going to do stop them". "If you are 4-0 up and forget to continue, you don't have respect for the competition or your opponent".
But while the scoreline threatened to put a dampener on the occasion - as did traffic problems on the road north from Burton - Clough said the club and their fans could still be proud.
Burton have since progressed to the third tier in League One, but Clough believes stopping Pep Guardiola's City, particularly when they travel to the Etihad on Wednesday, is an even tougher task. "That's why we had several thousands supporters here celebrating the fact we'll probably never be here again".
"I wanted to congratulate them for an incredible tournament", he said.
But it is not by accident that his side have seen off Aston Villa, Burnley, Nottingham Forest and Middlesbrough in this competition so far and he wants them to show what they can do.
Ahead of the first leg of the tie on Wednesday night, Clough spoke to the media, and made comparisons between the respective draws against the Manchester clubs. "We will take it seriously". "That's what we have done and that's why we are pleased".
