The title favourites consigned us to a first defeat in seven matches in the Premier League after running out 5-1 winners at the Lane.
Our French number one admitted that was a tough defeat to take, but quickly switched his focus to the KC Stadium.
“There are no words to describe the frustration after a game like that,” said Hugo.
“When City play at that level, it’s difficult. They were strong at 11 against 11 but at 10 against 11, there was too much space for them. We can’t accept a defeat like that, but we have to keep going.
“We have to be positive. Okay, when you lose at home like that, it’s never easy, but that’s football.
"We are in fifth place, three points behind Liverpool and anything could happen between now and the end of the season. We need to focus again and have a good reaction against Hull.”
