The City boss has guided the world's richest club to the quarter-finals of the UEFA Cup, but indifferent performances in the Barclays Premier League have done little to appease City fans worried about the appointment of a former Manchester United player.
But Hughes told Manchester City's official website: 'I said from Day One that I'm a professional football manager - my experience as a player and manager is there, it will always shape what you try to be in the future.
'People should understand what I am about. My focus is totally on making Manchester City a success in the future. I work all the hours that God gives us to make sure that happens.
'If everything comes together as we feel it will do, then we will be successful.
'It would give me enormous pleasure to be successful here. I could very easily have shied away from this role, but I wasn't prepared to do that because I knew what could happen here if I could get it going.'
City are 10th in the Premier League, but Hughes is pushing for a top seven finish to ensure UEFA Cup qualification.
The manager has been involved in strategy meetings with Manchester City executives this week and says he has been impressed with the progress the club has made since he moved from Blackburn Rovers last summer.
'It's been a huge year for everybody at the club,' he said. 'There have been brave changes when we could have pottered around and remained as we were.
'The way the club is now, the structure and the people in key positions, the club can only get better. It is being driven with pace.
'I've been very impressed by what I've been hearing, and the plans in place for the future will ensure that when success comes - and it will - it will be here for a long time.'
