Ipswich Town have made a solid start to life back in the top flight under O'Neil, collecting six points from their opening five matches to sit 11th in the early table.
The Blues have also been competitive in each of those fixtures, something O'Neil expects to continue as Ipswich look to establish themselves in the Premier League.
“I’m really confident in the group and I know what I’m going to see,” O'Neil said.
“Every single time I ask them to push and work, I get a fantastic response.”
O'Neil accepts that commitment alone cannot guarantee results, but believes the character of his squad will give Ipswich a platform to compete in every match.
“You can’t guarantee winning football matches. But I’m 100% confident that they’ll give everything in every game and that we’ll find a way to be in games and be competitive.”
The manager believes the decisive factor will then be whether Ipswich can produce the quality required to turn competitive performances into points.
“And then hopefully we’ll find that little bit of quality to get us across the line enough,” he added.
That was evident in Ipswich’s opening match of the season, when Jack Clarke scored a late winner to secure a 2-1 victory over Sunderland.
O'Neil sees such moments as essential if Town are to remain in the Premier League.
Ipswich return from the international break against Fulham at Portman Road on Saturday, with Marco Silva’s side still searching for their first victory of the campaign.
The Cottagers sit second bottom of the table, making the fixture an important early meeting between two teams expected to be involved in the battle for survival.
For O'Neil, however, the approach will remain unchanged. Ipswich must continue working, competing and putting themselves in positions where individual moments can decide matches.
Clarke’s late strike against Sunderland provided an early example of what the manager is looking for, and Ipswich will need more of those moments as the season progresses.
