Pep Guardiola believes his Manchester City side can still improve, despite making a record-breaking unbeaten start to the Premier League season, reports Sky Sports.

"We can do better," said Guardiola. "What I feel is that we still have a lot of things we can do better.

"If you analyse just the result, it's not a discussion but, in terms of playing and knowing what is going to happen in December with the schedule, we have to improve."
