New Manchester City manager Manuel Pellegrini was happy to get back to winning ways against Hull, but admitted there was still room for improvement.
Alvaro Negredo's header and a superb Yaya Toure free-kick sealed a 2-0 win over battling Hull at Etihad Stadium.
Pellegrini said City's hesitant start may have been a hangover from last Sunday's shock defeat at Cardiff.
"In the first-half we were without trust... but again at home we have a clean sheet - that's very pleasing."
Chilean Pellegrini added: "In pre-season we tried to work on different things, we experimented. But when we play in the Premier League we have to think more about the three points.
"So I am very pleased to win. We must improve though - we had many difficulties in the first-half.
"Hull is a good team. I was concerned that we failed to break them down in the first-half but 2-0 is a good scoreline. We can't win every game four or five nil - that's a good thing about the Premier League."
While expecting to complete a deal for Atletico Madrid defender Martin Demichelis before Monday's transfer deadline, Pellegrini said he was happy with his existing back line.
The 59-year-old added: "The clean sheet is very important for the whole team, for (goalkeeper) Joe Hart and for our defenders. They weren't very confident after the last game so it was important for them."
City next play Manchester United, after the international break.
